RND1, also known as Rho 6, is Rho-related GTPases form a distinct branch of the Rho family, since they differ from other Rho proteins in size, charge, and biochemical properties. It appears to be constitutively in the activated GTP-bound form and acts as negative regulators of actin assembly and of cell adhesion. It contributes to regulating the organization of the actin cytoskeleton in response to extracellular growth factors.
