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.5 It is encoded by the gene RAC2.6

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.6

Interactions

Rac2 has been shown to interact with ARHGDIA78 and Nitric oxide synthase 2A.9
