An ontology of human and animal behaviours. Neuro Behaviour Ontology GO 2023-02-21 definition If R <- P o Q is a defining property chain axiom, then it also holds that R -> P o Q. Note that this cannot be expressed directly in OWL is a defining property chain axiom If R <- P o Q is a defining property chain axiom, then (1) R -> P o Q holds and (2) Q is either reflexive or locally reflexive. A corollary of this is that P SubPropertyOf R. is a defining property chain axiom where second argument is reflexive is part of my brain is part of my body (continuant parthood, two material entities) my stomach cavity is part of my stomach (continuant parthood, immaterial entity is part of material entity) this day is part of this year (occurrent parthood) a core relation that holds between a part and its whole Everything is part of itself. Any part of any part of a thing is itself part of that thing. Two distinct things cannot be part of each other. Occurrents are not subject to change and so parthood between occurrents holds for all the times that the part exists. Many continuants are subject to change, so parthood between continuants will only hold at certain times, but this is difficult to specify in OWL. See http://purl.obolibrary.org/obo/ro/docs/temporal-semantics/ Parthood requires the part and the whole to have compatible classes: only an occurrent can be part of an occurrent; only a process can be part of a process; only a continuant can be part of a continuant; only an independent continuant can be part of an independent continuant; only an immaterial entity can be part of an immaterial entity; only a specifically dependent continuant can be part of a specifically dependent continuant; only a generically dependent continuant can be part of a generically dependent continuant. (This list is not exhaustive.) A continuant cannot be part of an occurrent: use 'participates in'. An occurrent cannot be part of a continuant: use 'has participant'. A material entity cannot be part of an immaterial entity: use 'has location'. A specifically dependent continuant cannot be part of an independent continuant: use 'inheres in'. An independent continuant cannot be part of a specifically dependent continuant: use 'bearer of'. part_of part of part of part_of http://www.obofoundry.org/ro/#OBO_REL:part_of has part my body has part my brain (continuant parthood, two material entities) my stomach has part my stomach cavity (continuant parthood, material entity has part immaterial entity) this year has part this day (occurrent parthood) a core relation that holds between a whole and its part Everything has itself as a part.

A specifically dependent continuant cannot have an independent continuant as part: use 'inheres in'. has_part has part has part has_part preceded by x is preceded by y if and only if the time point at which y ends is before or equivalent to the time point at which x starts. Formally: x preceded by y iff ω(y) <= α(x), where α is a function that maps a process to a start point, and ω is a function that maps a process to an end point. An example is: translation preceded_by transcription; aging preceded_by development (not however death preceded_by aging). Where derives_from links classes of continuants, preceded_by links classes of processes. Clearly, however, these two relations are not independent of each other. Thus if cells of type C1 derive_from cells of type C, then any cell division involving an instance of C1 in a given lineage is preceded_by cellular processes involving an instance of C. The assertion P preceded_by P1 tells us something about Ps in general: that is, it tells us something about what happened earlier, given what we know about what happened later. Thus it does not provide information pointing in the opposite direction, concerning instances of P1 in general; that is, that each is such as to be succeeded by some instance of P. Note that an assertion to the effect that P preceded_by P1 is rather weak; it tells us little about the relations between the underlying instances in virtue of which the preceded_by relation obtains. Typically we will be interested in stronger relations, for example in the relation immediately_preceded_by, or in relations which combine preceded_by with a condition to the effect that the corresponding instances of P and P1 share participants, or that their participants are connected by relations of derivation, or (as a first step along the road to a treatment of causality) that the one process in some way affects (for example, initiates or regulates) the other. is preceded by preceded_by preceded by precedes x precedes y if and only if the time point at which x ends is before or equivalent to the time point at which y starts.

This relation differs from BFO2:inheres_in in two respects: (1) it does not impose a range constraint, and thus it allows qualities of processes, as well as of information entities, whereas BFO2 restricts inheres_in to only apply to independent continuants (2) it is declared functional, i.e. something can only be a characteristic of one thing. characteristic of bearer of this apple is bearer of this red color this vase is bearer of this fragility Inverse of characteristic_of A bearer can have many dependents, and its dependents can exist for different periods of time, but none of its dependents can exist when the bearer does not exist. bearer_of is bearer of has characteristic has characteristic https://github.com/oborel/obo-relations/pull/284 participates in this blood clot participates in this blood coagulation this input material (or this output material) participates in this process this investigator participates in this investigation a relation between a continuant and a process, in which the continuant is somehow involved in the process participates_in participates in has participant this blood coagulation has participant this blood clot this investigation has participant this investigator this process has participant this input material (or this output material) a relation between a process and a continuant, in which the continuant is somehow involved in the process Has_participant is a primitive instance-level relation between a process, a continuant, and a time at which the continuant participates in some way in the process.

Note that this relation is now removed from BFO2020. disposition of is location of my head is the location of my brain this cage is the location of this rat a relation between two independent continuants, the location and the target, in which the target is entirely within the location Most location relations will only hold at certain times, but this is difficult to specify in OWL. See http://purl.obolibrary.org/obo/ro/docs/temporal-semantics/ location_of location of contained in Containment is location not involving parthood, and arises only where some immaterial continuant is involved. Containment obtains in each case between material and immaterial continuants, for instance: lung contained_in thoracic cavity; bladder contained_in pelvic cavity. Hence containment is not a transitive relation. If c part_of c1 at t then we have also, by our definition and by the axioms of mereology applied to spatial regions, c located_in c1 at t. Thus, many examples of instance-level location relations for continuants are in fact cases of instance-level parthood. For material continuants location and parthood coincide. Containment is location not involving parthood, and arises only where some immaterial continuant is involved. To understand this relation, we first define overlap for continuants as follows: c1 overlap c2 at t =def for some c, c part_of c1 at t and c part_of c2 at t. The containment relation on the instance level can then be defined (see definition): Intended meaning: domain: material entity range: spatial region or site (immaterial continuant) contained_in contained in contains contains located in my brain is located in my head this rat is located in this cage a relation between two independent continuants, the target and the location, in which the target is entirely within the location Location as a relation between instances: The primitive instance-level relation c located_in r at t reflects the fact that each continuant is at any given time associated with exactly one spatial region, namely its exact location. Following we can use this relation to define a further instance-level location relation - not between a continuant and the region which it exactly occupies, but rather between one continuant and another. c is located in c1, in this sense, whenever the spatial region occupied by c is part_of the spatial region occupied by c1. Note that this relation comprehends both the relation of exact location between one continuant and another which obtains when r and r1 are identical (for example, when a portion of fluid exactly fills a cavity), as well as those sorts of inexact location relations which obtain, for example, between brain and head or between ovum and uterus Most location relations will only hold at certain times, but this is difficult to specify in OWL. See http://purl.obolibrary.org/obo/ro/docs/temporal-semantics/ located_in located in This is redundant with the more specific 'independent and not spatial region' constraint. We leave in the redundant axiom for use with reasoners that do not use negation. This is redundant with the more specific 'independent and not spatial region' constraint.

Examples include the relationship between a multicellular organism and its integument, between an animal cell and its plasma membrane, and between a membrane bound organelle and its outer/bounding membrane. bounding layer of A 'has regulatory component activity' B if A and B are GO molecular functions (GO_0003674), A has_component B and A is regulated by B. has regulatory component activity A relationship that holds between a GO molecular function and a component of that molecular function that negatively regulates the activity of the whole. More formally, A 'has regulatory component activity' B iff :A and B are GO molecular functions (GO_0003674), A has_component B and A is negatively regulated by B. By convention GO molecular functions are classified by their effector function. Internal regulatory functions are treated as components. For example, NMDA glutmate receptor activity is a cation channel activity with positive regulatory component 'glutamate binding' and negative regulatory components including 'zinc binding' and 'magnesium binding'. has negative regulatory component activity A relationship that holds between a GO molecular function and a component of that molecular function that positively regulates the activity of the whole. More formally, A 'has regulatory component activity' B iff :A and B are GO molecular functions (GO_0003674), A has_component B and A is positively regulated by B. By convention GO molecular functions are classified by their effector function and internal regulatory functions are treated as components. So, for example calmodulin has a protein binding activity that has positive regulatory component activity calcium binding activity. Receptor tyrosine kinase activity is a tyrosine kinase activity that has positive regulatory component 'ligand binding'. has positive regulatory component activity A 'has component activity' B if A is A and B are molecular functions (GO_0003674) and A has_component B. has component activity w 'has process component' p if p and w are processes, w 'has part' p and w is such that it can be directly disassembled into into n parts p, p2, p3, ..., pn, where these parts are of similar type. has component process directly regulated by directly negatively regulated by directly positively regulated by This relation is designed for constructing compound molecular functions, typically in combination with one or more regulatory component activity relations. has effector activity David Osumi-Sutherland <= Primitive instance level timing relation between events before or simultaneous with David Osumi-Sutherland t1 simultaneous_with t2 iff:= t1 before_or_simultaneous_with t2 and not (t1 before t2) simultaneous with David Osumi-Sutherland X ends_after Y iff: end(Y) before_or_simultaneous_with end(X) ends after David Osumi-Sutherland starts_at_end_of X immediately_preceded_by Y iff: end(X) simultaneous_with start(Y) immediately preceded by David Osumi-Sutherland ends_at_start_of meets X immediately_precedes_Y iff: end(X) simultaneous_with start(Y) immediately precedes x overlaps y if and only if there exists some z such that x has part z and z part of y http://purl.obolibrary.org/obo/BFO_0000051 some (http://purl.obolibrary.org/obo/BFO_0000050 some ?Y) overlaps true Relation between a 'neuron projection bundle' and a region in which one or more of its component neuron projections either synapses to targets or receives synaptic input.

David Osumi-Sutherland connected to The label for this relation was previously connected to. I relabeled this to "continuous with". The standard notion of connectedness does not imply shared boundaries - e.g. Glasgow connected_to Edinburgh via M8; my patella connected_to my femur (via patellar-femoral joint) continuous with FMA:85972 lactation SubClassOf 'only in taxon' some 'Mammalia' x only in taxon y if and only if x is in taxon y, and there is no other organism z such that y!=z a and x is in taxon z. The original intent was to treat this as a macro that expands to 'in taxon' only ?Y - however, this is not necessary if we instead have supplemental axioms that state that each pair of sibling tax have a disjointness axiom using the 'in taxon' property - e.g. 'in taxon' some Eukaryota DisjointWith 'in taxon' some Eubacteria Chris Mungall only in taxon x is in taxon y if an only if y is an organism, and the relationship between x and y is one of: part of (reflexive), developmentally preceded by, derives from, secreted by, expressed. Chris Mungall Jennifer Deegan Connects a biological entity to its taxon of origin. in taxon A is spatially_disjoint_from B if and only if they have no parts in common There are two ways to encode this as a shortcut relation. The other possibility to use an annotation assertion between two classes, and expand this to a disjointness axiom. Chris Mungall Note that it would be possible to use the relation to label the relationship between a near infinite number of structures - between the rings of saturn and my left earlobe. The intent is that this is used for parsiomoniously for disambiguation purposes - for example, between siblings in a jointly exhaustive pairwise disjointness hierarchy BFO_0000051 exactly 0 (BFO_0000050 some ?Y) spatially disjoint from https://github.com/obophenotype/uberon/wiki/Part-disjointness-Design-Pattern a 'toe distal phalanx bone' that is connected to a 'toe medial phalanx bone' (an interphalangeal joint *connects* these two bones). a is connected to b if and only if a and b are discrete structure, and there exists some connecting structure c, such that c connects a and b connected to https://github.com/obophenotype/uberon/wiki/Connectivity-Design-Pattern https://github.com/obophenotype/uberon/wiki/Modeling-articulations-Design-Pattern The M8 connects Glasgow and Edinburgh a 'toe distal phalanx bone' that is connected to a 'toe medial phalanx bone' (an interphalangeal joint *connects* these two bones). c connects a if and only if there exist some b such that a and b are similar parts of the same system, and c connects b, specifically, c connects a with b. When one structure connects two others it unites some aspect of the function or role they play within the system. connects https://github.com/obophenotype/uberon/wiki/Connectivity-Design-Pattern https://github.com/obophenotype/uberon/wiki/Modeling-articulations-Design-Pattern a is attached to part of b if a is attached to b, or a is attached to some p, where p is part of b. attached to part of (anatomical structure to anatomical structure) attached to part of true Relation between an arterial structure and another structure, where the arterial structure acts as a conduit channeling fluid, substance or energy. Individual ontologies should provide their own constraints on this abstract relation. For example, in the realm of anatomy this should hold between an artery and an anatomical structure supplies Relation between an collecting structure and another structure, where the collecting structure acts as a conduit channeling fluid, substance or energy away from the other structure. Individual ontologies should provide their own constraints on this abstract relation. For example, in the realm of anatomy this should hold between a vein and an anatomical structure drains w 'has component' p if w 'has part' p and w is such that it can be directly disassembled into into n parts p, p2, p3, ..., pn, where these parts are of similar type. The definition of 'has component' is still under discussion. The challenge is in providing a definition that does not imply transitivity. For use in recording has_part with a cardinality constraint, because OWL does not permit cardinality constraints to be used in combination with transitive object properties. In situations where you would want to say something like 'has part exactly 5 digit, you would instead use has_component exactly 5 digit. has component x develops from y if and only if either (a) x directly develops from y or (b) there exists some z such that x directly develops from z and z develops from y Chris Mungall David Osumi-Sutherland Melissa Haendel Terry Meehan This is the transitive form of the develops from relation develops from inverse of develops from Chris Mungall David Osumi-Sutherland Terry Meehan develops into Candidate definition: x directly_develops from y if and only if there exists some developmental process (GO:0032502) p such that x and y both participate in p, and x is the output of p and y is the input of p, and a substantial portion of the matter of x comes from y, and the start of x is coincident with or after the end of y.

Chris Mungall has function realized in For compatibility with BFO, this relation has a shortcut definition in which the expression "capable of some P" expands to "bearer_of (some realized_by only P)". capable of c stands in this relationship to p if and only if there exists some p' such that c is capable_of p', and p' is part_of p.

In contrast, a butterfly flying close to a flower is not considered adjacent, unless there are any touching parts. The epidermis layer of a vertebrate is adjacent to the dermis. The plasma membrane of a cell is adjacent to the cytoplasm, and also to the cell lumen which the cytoplasm occupies. The skin of the forelimb is adjacent to the skin of the torso if these are considered anatomical subdivisions with a defined border. Otherwise a relation such as continuous_with would be used. x adjacent to y if and only if x and y share a boundary.

Chris Mungall indirectly activates indirectly positively regulates p indirectly negatively regulates q iff p is indirectly causally upstream of q and p negatively regulates q. Chris Mungall indirectly inhibits indirectly negatively regulates This branch of the ontology deals with causal relations between entities. It is divided into two branches: causal relations between occurrents/processes, and causal relations between material entities. We take an 'activity flow-centric approach', with the former as primary, and define causal relations between material entities in terms of causal relations between occurrents. To define causal relations in an activity-flow type network, we make use of 3 primitives: * Temporal: how do the intervals of the two occurrents relate? * Is the causal relation regulatory? * Is the influence positive or negative? The first of these can be formalized in terms of the Allen Interval Algebra. Informally, the 3 bins we care about are 'direct', 'indirect' or overlapping. Note that all causal relations should be classified under a RO temporal relation (see the branch under 'temporally related to'). Note that all causal relations are temporal, but not all temporal relations are causal. Two occurrents can be related in time without being causally connected. We take causal influence to be primitive, elucidated as being such that has the upstream changed, some qualities of the donwstream would necessarily be modified. For the second, we consider a relationship to be regulatory if the system in which the activities occur is capable of altering the relationship to achieve some objective. This could include changing the rate of production of a molecule. For the third, we consider the effect of the upstream process on the output(s) of the downstream process. If the level of output is increased, or the rate of production of the output is increased, then the direction is increased. Direction can be positive, negative or neutral or capable of either direction. Two positives in succession yield a positive, two negatives in succession yield a positive, otherwise the default assumption is that the net effect is canceled and the influence is neutral. Each of these 3 primitives can be composed to yield a cross-product of different relation types. Chris Mungall Do not use this relation directly. It is intended as a grouping for a diverse set of relations, all involving cause and effect. causally related to p is causally upstream of q iff p is causally related to q, the end of p precedes the end of q, and p is not an occurrent part of q.

Chris Mungall immediately causally upstream of p is 'causally upstream or within' q iff p is causally related to q, and the end of p precedes, or is coincident with, the end of q.

This relation and all sub-relations can be applied to either (1) pairs of entities that are interacting at any moment of time (2) populations or species of entity whose members have the disposition to interact (3) classes whose members have the disposition to interact.

In this case the quality is 'lacking all parts of type' - it is a (relational) quality of the spermatocyte, and it is with respect to instances of 'aster'. One of the popular requirements of PATO is that it continue to support 'absent', so we need to relate statements which use this quality to the 'lacking all parts of type' quality. reciprocal of A diagnostic testing device utilizes a specimen.

A process may have a succession of participants at different phases of its unfolding. Thus there may be different players on the field at different times during the course of a football game; but the process which is the entire game s-depends_on all of these players nonetheless. Some temporal parts of this process will s-depend_on on only some of the players. Occurrent doesn't have a closure axiom because the subclasses don't necessarily exhaust all possibilites. An example would be the sum of a process and the process boundary of another process. Simons uses different terminology for relations of occurrents to regions: Denote the spatio-temporal location of a given occurrent e by 'spn[e]' and call this region its span. We may say an occurrent is at its span, in any larger region, and covers any smaller region. Now suppose we have fixed a frame of reference so that we can speak not merely of spatio-temporal but also of spatial regions (places) and temporal regions (times). The spread of an occurrent, (relative to a frame of reference) is the space it exactly occupies, and its spell is likewise the time it exactly occupies. We write 'spr[e]' and `spl[e]' respectively for the spread and spell of e, omitting mention of the frame. An occurrent is an entity that unfolds itself in time or it is the instantaneous boundary of such an entity (for example a beginning or an ending) or it is a temporal or spatiotemporal region which such an entity occupies_temporal_region or occupies_spatiotemporal_region.

We write 'spr[e]' and `spl[e]' respectively for the spread and spell of e, omitting mention of the frame. An occurrent is an entity that unfolds itself in time or it is the instantaneous boundary of such an entity (for example a beginning or an ending) or it is a temporal or spatiotemporal region which such an entity occupies_temporal_region or occupies_spatiotemporal_region.

(axiom label in BFO2 Reference: [083-003]) BFO 2 Reference: The realm of occurrents is less pervasively marked by the presence of natural units than is the case in the realm of independent continuants. Thus there is here no counterpart of ‘object’. In BFO 1.0 ‘process’ served as such a counterpart. In BFO 2.0 ‘process’ is, rather, the occurrent counterpart of ‘material entity’. Those natural – as contrasted with engineered, which here means: deliberately executed – units which do exist in the realm of occurrents are typically either parasitic on the existence of natural units on the continuant side, or they are fiat in nature. Thus we can count lives; we can count football games; we can count chemical reactions performed in experiments or in chemical manufacturing. We cannot count the processes taking place, for instance, in an episode of insect mating behavior.Even where natural units are identifiable, for example cycles in a cyclical process such as the beating of a heart or an organism’s sleep/wake cycle, the processes in question form a sequence with no discontinuities (temporal gaps) of the sort that we find for instance where billiard balls or zebrafish or planets are separated by clear spatial gaps. Lives of organisms are process units, but they too unfold in a continuous series from other, prior processes such as fertilization, and they unfold in turn in continuous series of post-life processes such as post-mortem decay. Clear examples of boundaries of processes are almost always of the fiat sort (midnight, a time of death as declared in an operating theater or on a death certificate, the initiation of a state of war) (iff (Process a) (and (Occurrent a) (exists (b) (properTemporalPartOf b a)) (exists (c t) (and (MaterialEntity c) (specificallyDependsOnAt a c t))))) // axiom label in BFO2 CLIF: [083-003] process p is a process = Def. p is an occurrent that has temporal proper parts and for some time t, p s-depends_on some material entity at t.

Thus ‘professor’, defined as follows,b instance_of professor at t =Def. there is some c, c instance_of professor role & c inheres_in b at t.denotes a non-rigid universal and so also do ‘nurse’, ‘student’, ‘colonel’, ‘taxpayer’, and so forth. (These terms are all, in the jargon of philosophy, phase sortals.) By using role terms in definitions, we can create a BFO conformant treatment of such entities drawing on the fact that, while an instance of professor may be simultaneously an instance of trade union member, no instance of the type professor role is also (at any time) an instance of the type trade union member role (any more than any instance of the type color is at any time an instance of the type length).If an ontology of employment positions should be defined in terms of roles following the above pattern, this enables the ontology to do justice to the fact that individuals instantiate the corresponding universals – professor, sergeant, nurse – only during certain phases in their lives. b is a role means: b is a realizable entity & b exists because there is some single bearer that is in some special physical, social, or institutional set of circumstances in which this bearer does not have to be& b is not such that, if it ceases to exist, then the physical make-up of the bearer is thereby changed.

Users are invited to propose new subcategories of Material Entity. BFO 2 Reference: ‘Matter’ is intended to encompass both mass and energy (we will address the ontological treatment of portions of energy in a later version of BFO). A portion of matter is anything that includes elementary particles among its proper or improper parts: quarks and leptons, including electrons, as the smallest particles thus far discovered; baryons (including protons and neutrons) at a higher level of granularity; atoms and molecules at still higher levels, forming the cells, organs, organisms and other material entities studied by biologists, the portions of rock studied by geologists, the fossils studied by paleontologists, and so on.Material entities are three-dimensional entities (entities extended in three spatial dimensions), as contrasted with the processes in which they participate, which are four-dimensional entities (entities extended also along the dimension of time).According to the FMA, material entities may have immaterial entities as parts – including the entities identified below as sites; for example the interior (or ‘lumen’) of your small intestine is a part of your body.

When this term is used for annotation, it indicates that no information was available about the molecular function of the gene product annotated as of the date the annotation was made; the evidence code 'no data' (ND), is used to indicate this. Despite its name, this is not a type of 'function' in the sense typically defined by upper ontologies such as Basic Formal Ontology (BFO).

While a broader definition of behavior encompassing plants and single cell organisms would be justified on the basis of some usage (see PMID:20160973 for discussion), GO uses a tight definition that limits behavior to animals and to responses involving the nervous system, excluding plant responses that GO classifies under development, and responses of unicellular organisms that has general classifications for covering the responses of cells in multicellular organisms (e.g. cell chemotaxis). behavior mating behavior courtship behavior copulation rhythmic behavior circadian rhythm groom grooming behavior locomotory behavior fly flight behavior https://github.com/geneontology/go-ontology/issues/18547 See also the biological process term 'behavior ; GO:0007610'. feeding behavior visual behavior chemosensory behavior mechanosensory behavior blood circulation regulation of heart contraction male courtship behavior female courtship behavior https://github.com/geneontology/go-ontology/issues/23112 protein localization A process that emerges from two or more causally-connected macromolecular activities and has evolved to achieve a biological objective. A biological process is an evolved process Note that, in addition to forming the root of the biological process ontology, this term is recommended for use for the annotation of gene products whose biological process is unknown. When this term is used for annotation, it indicates that no information was available about the biological process of the gene product annotated as of the date the annotation was made; the evidence code 'no data' (ND), is used to indicate this. biological process biological_process Note that metabolic processes do not include single functions or processes such as protein-protein interactions, protein-nucleic acids, nor receptor-ligand interactions. metabolic process steroid metabolic process bile acid metabolic process This term was moved out from being a child of 'cellular process' because it is a cell population-level process, and cellular processes are restricted to those processes that involve individual cells.

Note also that sexual reproduction may be seen as the regular alternation, in the life cycle of haplontic, diplontic and diplohaplontic organisms, of meiosis and fertilization which provides for the production offspring. In diplontic organisms there is a life cycle in which the products of meiosis behave directly as gametes, fusing to form a zygote from which the diploid, or sexually reproductive polyploid, adult organism will develop. In diplohaplontic organisms a haploid phase (gametophyte) exists in the life cycle between meiosis and fertilization (e.g. higher plants, many algae and Fungi); the products of meiosis are spores that develop as haploid individuals from which haploid gametes develop to form a diploid zygote; diplohaplontic organisms show an alternation of haploid and diploid generations. In haplontic organisms meiosis occurs in the zygote, giving rise to four haploid cells (e.g. many algae and protozoa), only the zygote is diploid and this may form a resistant spore, tiding organisms over hard times. sexual reproduction neural tube development circadian sleep/wake cycle process cellular process involved in reproduction in multicellular organism reproductive process digestive system process regulation of anatomical structure morphogenesis regulation of signaling Note that a signal is any variable property or parameter that serves to convey information, and may be a physical entity such as a gene product or small molecule, a photon, or a change in state such as movement or voltage change. signaling positive regulation of signaling negative regulation of signaling signal release cell junction peptide hormone secretion https://github.com/geneontology/go-ontology/issues/11255#issuecomment-426191045 insulin secretion https://github.com/geneontology/go-ontology/issues/22178 hemopoiesis cell differentiation regulation of ossification negative regulation of ossification The outer membrane (of gram negative bacteria) or cell wall (of yeast or Gram positive bacteria) are defined as parts of this structure, see 'external encapsulating structure part'. external encapsulating structure regulation of cell migration positive regulation of cell migration negative regulation of cell migration defecation sleep peristalsis See also the biological process term 'behavior ; GO:0007610'. adult behavior cytoplasmic vesicle membrane transmembrane collagen trimer extracellular matrix organelle membrane auditory behavior regulation of cellular metabolic process negative regulation of cellular metabolic process positive regulation of cellular metabolic process regulation of cellular biosynthetic process negative regulation of cellular biosynthetic process positive regulation of cellular biosynthetic process regulation of cellular catabolic process negative regulation of cellular catabolic process positive regulation of cellular catabolic process cytoplasmic vesicle regulation of nervous system process negative regulation of nervous system process positive regulation of nervous system process vesicle locomotion involved in locomotory behavior positive regulation of insulin secretion Note that this term is in the subset of terms that should not be used for direct gene product annotation.

Acceptable experimental methods include stringent protein purification followed by detection of protein interaction. The following methods should be considered non-acceptable: simple immunoprecipitation, pull-down experiments from cell extracts without further purification, colocalization and 2-hybrid screening. Interactions that should not be captured as protein complexes include: 1) enzyme/substrate, receptor/ligand or any similar transient interactions, unless these are a critical part of the complex assembly or are required e.g. for the receptor to be functional; 2) proteins associated in a pull-down/co-immunoprecipitation assay with no functional link or any evidence that this is a defined biological entity rather than a loose-affinity complex; 3) any complex where the only evidence is based on genetic interaction data; 4) partial complexes, where some subunits (e.g. transmembrane ones) cannot be expressed as recombinant proteins and are excluded from experiments (in this case, independent evidence is necessary to find out the composition of the full complex, if known). Interactions that may be captured as protein complexes include: 1) enzyme/substrate or receptor/ligand if the complex can only assemble and become functional in the presence of both classes of subunits; 2) complexes where one of the members has not been shown to be physically linked to the other(s), but is a homologue of, and has the same functionality as, a protein that has been experimentally demonstrated to form a complex with the other member(s); 3) complexes whose existence is accepted based on localization and pharmacological studies, but for which experimental evidence is not yet available for the complex as a whole.
