Rac2 (Ras-related C3 botulinum toxin substrate 2) is a small (~21 kDa) signaling G protein (to be specific a GTPase) and is a member of the Rac subfamily of the family Rho family of GTPases. It is encoded by the gene RAC2.Members of Rho family of GTPases appear to regulate a diverse array of cellular events including the control of cell growth cytoskeletal reorganization and the activation of protein kinases.
