RAC3 (Rac Family Small GTPase 3) is a Protein Coding gene. Among its related pathways are p70S6K Signaling and Focal Adhesion. The protein encoded by RAC3 is a GTPase which belongs to the RAS superfamily of small GTP-binding proteins. Members of this superfamily appear to regulate a diverse array of cellular events, including the control of cell growth, cytoskeletal reorganization, and the activation of protein kinases. Alternative splicing results in multiple transcript variants.
