RGS3 (regulator of G protein signaling 3) is a 519-residue protein that is widely expressed in many tissues and cells. The protein contains an RGS domain near the carboxy terminus that serves as a GTPase-activating protein (GAP). RGS3 negatively regulates the activation of Gia and Gaq. A truncated RGS3 (RGS3T), with its N-terminal 313 residues removed, has been shown to negatively regulate acenylyl cyclase and PLC. RGS3T may be localized in the nucleus and RGS3 is found in cytoplasm. Translocation to membrane is important for the RGS proteins to interact with heterotrimeric G proteins.
