Regulator of G protein signaling (RGS) domain superfamily; The RGS domain is an essential part of the Regulator of G-protein Signaling (RGS) protein family, a diverse group of multifunctional proteins that regulate cellular signaling events downstream of G-protein coupled receptors (GPCRs). RGS proteins play critical regulatory roles as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. While inactive, G-alpha-subunits bind GDP, which is released and replaced by GTP upon agonist activation. GTP binding leads to dissociation of the alpha-subunit and the beta-gamma-dimer, allowing them to interact with effectors molecules and propagate signaling cascades associated with cellular growth, survival, migration, and invasion. Deactivation of the G-protein signaling controlled by the RGS domain accelerates GTPase activity of the alpha subunit by hydrolysis of GTP to GDP, which results in the reassociation of the alpha-subunit with the beta-gamma-dimer and thereby inhibition of downstream activity. As a major G-protein regulator, RGS domain containing proteins are involved in many crucial cellular processes such as regulation of intracellular trafficking, glial differentiation, embryonic axis formation, skeletal and muscle development, and cell migration during early embryogenesis. RGS proteins are also involved in apoptosis and cell proliferation, as well as modulation of cardiac development. Several RGS proteins can fine-tune immune responses, while others play important roles in neuronal signals modulation. Some RGS proteins are principal elements needed for proper vision.

Regulator of G protein signaling (RGS) domain found in the Rho guanine nucleotide exchange factor (GEF), p115 RhoGEF; The RGS (Regulator of G-protein Signaling) domain is an essential part of the p115RhoGEF protein, a member of the RhoGEF (Rho guanine nucleotide exchange factor) subfamily of the RGS protein family. The RhoGEFs are peripheral membrane proteins that regulate essential cellular processes, including cell shape, cell migration, cell cycle progression of cells, and gene transcription by linking signals from heterotrimeric G-alpha12/13 protein-coupled receptors to Rho GTPase activation, leading to various cellular responses, such as actin reorganization and gene expression. The RhoGEF subfamily includes p115RhoGEF, LARG, PDZ-RhoGEF and its rat specific splice variant GTRAP48. The RGS domain of RhoGEFs has very little sequence similarity with the canonical RGS domain of the RGS proteins and is often refered to as RH (RGS Homology) domain. In addition to being a G-alpha13/12 effector, the p115RhoGEF protein also functions as a GTPase-activating protein (GAP) for G-alpha13.

Regulator of G protein signalling-like domain; Members of this family adopt a structure consisting of twelve helices that fold into a compact domain that contains the overall structural scaffold observed in other RGS proteins and three additional helical elements that pack closely to it. Helices 1-9 comprise the RGS (pfam00615) fold, in which helices 4-7 form a classic antiparallel bundle adjacent to the other helices. Like other RGS structures, helices 7 and 8 span the length of the folded domain and form essentially one continuous helix with a kink in the middle. Helices 10-12 form an apparently stable C-terminal extension of the structural domain, and although other RGS proteins lack this structure, these elements are intimately associated with the rest of the structural framework by hydrophobic interactions. Members of the family bind to active G-alpha proteins, promoting GTP hydrolysis by the alpha subunit of heterotrimeric G proteins, thereby inactivating the G protein and rapidly switching off G protein-coupled receptor signalling pathways.
