GO Classification
Functions
actin filament binding / MAP-kinase scaffold activity / molecular adaptor activity / small GTPase binding
Processes
cell migration / fibroblast migration / mitotic actomyosin contractile ring assembly actin filament organization / podocyte development / positive regulation of MAPK cascade / regulation of mitotic cell cycle
Components
apical plasma membrane / basolateral plasma membrane / cell cortex / cortical actin cytoskeleton / cytoplasmic side of plasma membrane / ribonucleoprotein complex
General Function
Plays a crucial role in regulating the dynamics and assembly of the actin cytoskeleton. Binds to activated CDC42 but does not stimulate its GTPase activity. It associates with calmodulin. Could serve as an assembly scaffold for the organization of a multimolecular complex that would interface incoming signals to the reorganization of the actin cytoskeleton at the plasma membrane. May promote neurite outgrowth (PubMed:15695813). May play a possible role in cell cycle regulation by contributing to cell cycle progression after DNA replication arrest (PubMed:20883816)
