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].	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].	Domain

This family contains, amongst other G-protein-coupled receptors (GCPRs), members of the opsin family, which have been considered to be typical members of the rhodopsin superfamily. They share several motifs, mainly the seven transmembrane helices, GCPRs of the rhodopsin superfamily. All opsins bind a chromophore, such as 11-cis-retinal. The function of most opsins other than the photoisomerases is split into two steps: light absorption and G-protein activation. Photoisomerases, on the other hand, are not coupled to G-proteins - they are thought to generate and supply the chromophore that is used by visual opsins [1].	Domain
