A cytoskeleton is a complex, dynamic network of interlinking protein filaments that extends from the cell nucleus to the cell membrane. Actin filaments, composed of the abundant actin protein, are a main component of the cytoskeleton, playing a key role muscle contraction.This pathway was inferred from Homo sapiens pathway [http://www.wikipathways.org/index.php?title=Pathway:WP51&oldid=20783 WP51(r20783)] with a 94% conversion rate.cell adhesion signaling pathwayPW:0000648Pathway Ontology
