Rho-GTPase-activating protein 5 (p190-B, ARHGAP5, RHOGAP5)

Function: - GTPase-activating protein for all rho subfamily proteins - formation of a complex between ras-GAP & ARHGAP5 in growth-stimulated cells may allow coupling of signalling pathways that involve ras & rho GTPases - may play a role in the reduction of the p21ras GTPase-activating potential of p120GAP Structure: - contains 4 FF domains - contains 1 Rho-GAP domain Compartment: - cytoplasm, peripheral membrane - membrane-associated when found in fibrillar patterns that colocalize with the alpha5-beta1 integrin receptor (ITGA5/ITGB1) for fibronectin Expression: expressed in kidney, brain, liver & lung
