A PF00503 G-alpha G-protein alpha subunit Domain G proteins couple receptors of extracellular signals to intracellular signaling pathways. The G protein alpha subunit binds guanyl nucleotide and is a weak GTPase. A set of residues that are unique to G-alpha as compared to its ancestor the Arf-like family form a ring of residues centered on the nucleotide binding site [3]. A Ggamma is found fused to an inactive Galpha in the Dictyostelium protein gbqA [3]. PFAM PF00503
E PF00615 RGS Regulator of G protein signaling domain Domain RGS family members are GTPase-activating proteins for heterotrimeric G-protein alpha-subunits. PFAM PF00615
