Rho gtpases constitute a subfamily of the ras superfamily of small gtpases. Small gtpases of the ras superfamily consist of several subfamilies, including the ras, rho, adp ribosylation factor arf, and rab gtpases, all of which are key regulators in the signaling pathways that control diverse cellular and developmental events such as differentiation, cell division, vesicle transport, nuclear assembly. Small gtpases are tightly regulated molecular switches that make binary onoff decisions through controlled loading of gtp activation and hydrolysis of gtp to gdp inactivation.
