CC   -!- FUNCTION: Inactive GDP-bound Rho GTPases reside in the cytosol, are
CC       found in a complex with Rho GDP-dissociation inhibitors (Rho GDIs), and
CC       are released from the GDI protein in order to translocate to membranes
CC       upon activation. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Membrane {ECO:0000250};
CC       Peripheral membrane protein {ECO:0000250}. Note=Associated with the
CC       membrane when activated.
CC   -!- SIMILARITY: Belongs to the small GTPase superfamily. Rho family.
CC       {ECO:0000305}.
