Q 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
B PF00400 WD40 WD domain, G-beta repeat Repeat
B PF00400 WD40 WD domain, G-beta repeat Repeat
B PF00400 WD40 WD domain, G-beta repeat Repeat
A PF00615 RGS Regulator of G protein signaling domain Domain RGS family members are GTPase-activating proteins for heterotrimeric G-protein alpha-subunits. PFAM PF00615
B PF00400 WD40 WD domain, G-beta repeat Repeat
A PF00169 PH PH domain Domain PH stands for pleckstrin homology. PFAM PF00169
G PF00631 G-gamma GGL domain Domain G-protein gamma like domains (GGL) are found in the gamma subunit of the heterotrimeric G protein complex and in regulators of G protein signaling (RGS) proteins [1]. It is also found fused to an inactive Galpha in the Dictyostelium protein gbqA [2]. G-gamma likely shares a common origin with the helical N-terminal unit of G-beta [2]. All organisms that posses a G-beta possess a G-gamma [2]. PFAM PF00631
