Predicted to enable GTP binding activity; GTPase activity; and protein kinase binding activity. Predicted to be involved in actin filament organization; regulation of actin cytoskeleton organization; and signal transduction. Predicted to act upstream of or within small GTPase-mediated signal transduction. Predicted to be located in membrane. Predicted to be active in cytosol and plasma membrane. Orthologous to human RND3 (Rho family GTPase 3).
