a multidomain, adaptor protein that regulates cellular processes, such as migration and protrusive activity, by bringing together various signaling molecules, including PIX, PAK, and paxillin. Phosphorylation on Ser-709 increases its binding to paxillin and regulates cellular protrusions. Possesses ADP-ribosylation factor (ARF) GTPase-activating protein (GAP) activity. Functions as part of a multi-molecular signaling complex that regulates membrane protrusions and cell migration. Regulates PLC-gamma activation by c-Src and integrates signal transduction by G protein coupled receptors (GPCR)s and tyrosine kinase receptors (TKRs). Note: This description may include information from UniProtKB.
