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 ARHGDIA[7][8] and Nitric oxide synthase 2A.[9]
