The type I IFNs (IFNα family, IFNβ, IFNω, IFNε and IFNκ) all bind to and signal via the type I IFN receptor complex. The type I receptor consists of two main IFNAR1, IFNAR2c receptor chains and other accessory proteins. The pathway above (WP585) describes the Type I Interferon signaling pathways and shows both classical IFN signaling via the JAK-STAT pathway (dark lines) and other non-canonical IFN signaling pathways.
Proteins on this pathway have targeted assays available via the [https://assays.cancer.gov/available_assays?wp_id=WP585 CPTAC Assay Portal]c3da39cf0C3GSHP1b3eea3ebaaf6ffca05c1fb20INTERFERON
