RAC2

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.

Interactions
Rac2 has been shown to interact with ARHGDIA and Nitric oxide synthase 2A.
