Selective Inhibition of G Protein-Mediated Pathways Using RGS Domainsmembers of G protein α subunits and, in most cases, act as GTPase activating proteins (GAPs). RGS proteins interact with activated forms of Gα subunits through RGS domain of about 120 amino acids. Thus, the overexpression of the RGS domain in cells can specifically block the signalling pathways that
