1、Rho belongs to the Ras super family of low molecular weight GTPases. Fifteen Rho proteins have already been characterized and divided into three sub-families; the first includes Rho （A, B, C）, the second, Rnd 1-3 and the third which includes Rac 1-3, RhoG, Cdc42Hs, Rho/TTF. TC10 and Chp. Rho acts as a molecular switch which turns on of off various intracellular signaling pathways such as ACK, PAKs, MEKKs ROCK. Rho is active when bound to GTP and inactive when bound to GDP. It is also known to participate in many physiological activities including cell migration, adhesion, cytokinesis, proliferation, differentiation and apoptosis and to a greater extend cell transformation.。
