Binder of Rho GTPases 2, BORG2, CDC42 effector protein (Rho GTPase binding) 3, Cdc42 effector protein 3, CEP3, CRIB containing BORG2 protein, MSE55 related Cdc42 binding protein, MSE55 related protein, UB1.
CDC42EP3 is probably involved in the organization of the actin cytoskeleton. May act downstream of CDC42 to induce actin filament assembly leading to cell shape changes. It induces pseudopodia formation in fibroblasts.
