function:Lacks intrinsic GTPase activity. Has a low affinity for GDP, and constitutively binds GTP. Controls rearrangements of the actin cytoskeleton. Induces the Rac-dependent neuritic process formation in part by disruption of the cortical actin filaments. Causes the formation of many neuritic processes from the cell body with disruption of the cortical actin filaments.,similarity:Belongs to the small GTPase superfamily. Rho family.,subunit:Binds GRB7 and PLXNB1. Interacts with UBXD5.,tissue specificity:Mostly expressed in brain and liver.,
Cell membrane ; Lipid-anchor ; Cytoplasmic side . Cytoplasm, cytoskeleton .
Mostly expressed in brain and liver.
