They share a common domain architecture, containing, beside the RGS domain, a DEP domain and a GGL (G-protein gamma subunit-like ) domain. RGS proteins are GTPase-activating (GAP) proteins of heterotrimeric G proteins by increasing the rate of GTP hydrolysis of the alpha subunit. The fungal homologs, like yeast Sst2, share a related common domain architecture, containing RGS and DEP domains. Sst2 has been identified as the principal regulator of mating pheromone signaling and recently the DEP domain of Sst2 has been shown to be necessary and sufficient to mediate receptor interaction.

Domain found in Dishevelled, Egl-10, and Pleckstrin (DEP); The DEP domain is responsible for mediating intracellular protein targeting and regulation of protein stability in the cell. The DEP domain is present in a number of signaling molecules, including Regulator of G protein Signaling (RGS) proteins, and has been implicated in membrane targeting. New findings in yeast, however, demonstrate a major role for a DEP domain in mediating the interaction of an RGS protein to the C-terminal tail of a GPCR, thus placing RGS in close proximity with its substrate G protein alpha subunit.

Regulator of G protein signaling (RGS) domain found in the RGS20 protein; The RGS (Regulator of G-protein Signaling) domain is an essential part of the RGS20 protein (also known as RGSZ1), a member of the RZ subfamily of the RGS protein family. They are 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. Deactivation of G-protein signaling is controlled by the RGS domain, which accelerates GTPase activity of the alpha subunit by hydrolysis of GTP to GDP resulting in reassociation of the alpha-subunit with the beta-gamma-dimer and inhibition of downstream activity. As a major G-protein regulator, the 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. The RZ subfamily of RGS proteins include RGS17, RGS19 (former GAIP), and the splice variant of RGS20, Ret-RGS. RGS20 is expressed exclusively in brain, with the highest concentrations in the temporal lobe and the caudate nucleus and may play a role in signaling regulation in these brain regions. RGS20 acts as a GAP of both G-alpha-z and G-alpha-I and controls signaling in the mu opioid receptor pathway.

RGS proteins play critical regulatory roles as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha subunits. The RGS domain controls G-protein signaling by accelerating the GTPase activity of the G-alpha subunit which leads to G protein deactivation and promotes desensitization. As a major G-protein regulator, RGS domain containing proteins are involved in many crucial cellular processes. RGS3 induces apoptosis when overexpressed and is involved in cell migration through interaction with the Ephrin receptor.

Regulator of G protein signaling (RGS) domain found in the RGS5 protein; The RGS (Regulator of G-protein Signaling) domain is an essential part of the RGS5 protein. RGS5 is member of the R4/RGS subfamily of the RGS 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. The RGS domain controls G-protein signaling by accelerating the GTPase activity of the G-alpha subunit which leads to G protein deactivation and promotes desensitization. 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. Two splice isoforms of RGS5 has been found: RGS5L (long) which is expressed in smooth muscle cells (pericytes) and heart and RGS5S (short) which is highly expressed in the ciliary body of the eye, kidney, brain, spleen, skeletal muscle, and small intestine. Outside of the GPCR pathway, RGS5 interacts with the 14-3-3 protein.

Domain found in Dishevelled, Egl-10, and Pleckstrin (DEP); The DEP domain is responsible for mediating intracellular protein targeting and regulation of protein stability in the cell. The DEP domain is present in a number of signaling molecules, including Regulator of G protein Signaling (RGS) proteins, and has been implicated in membrane targeting. New findings in yeast, however, demonstrate a major role for a DEP domain in mediating the interaction of an RGS protein to the C-terminal tail of a GPCR, thus placing RGS in close proximity with its substrate G protein alpha subunit.

DEP (Dishevelled, Egl-10, and Pleckstrin) domain found in fungal RhoGEF (GDP/GTP exchange factor) PIKfyve-like proteins. PIKfyve contains N-terminal Fyve finger and DEP domains, a central chaperonin-like domain and a C-terminal PIPK (phosphatidylinositol phosphate kinase) domain. PIKfyve-like proteins are important phosphatidylinositol (3)-monophosphate (PtdIns(3)P)-5-kinases, producing PtdIns(3,5)P2, which plays a major role in multivesicular body (MVB) sorting and control of retrograde traffic from the vacuole back to the endosome and/or Golgi. PIKfyve itself has been shown to be play a role in regulating early-endosome-to-trans-Golgi network (TGN) retrograde trafficking.

Regulator of G protein signaling domain (RGS) found in G protein-coupled receptor kinase 5 (GRK5); The RGS domain is an essential part of the GRK5 (G protein-coupled receptor kinase 5) protein, a membrane-associated serine/threonine protein kinases which phosphorylates G protein-coupled receptors (GPCRs) upon agonist stimulation. This phosphorylation initiates beta-arrestin-mediated receptor desensitization, internalization, and signaling events. GRK5 is a member of the GRK kinase family which include three major subfamilies: the GRK4 subfamily (GRK4, GRK5 and GRK6), the rhodopsin kinase or visual GRK subfamily (GRK1 and GRK7), and the beta-adrenergic receptor kinases subfamily (GRK2/GRK3). The RGS domain of the GRKs has very little sequence similarity with the canonical RGS domain of the RGS proteins and therefore is often refered to as the RH (RGS Homology) domain. RGS proteins regulate many aspects of embryonic development such as glial differentiation, embryonic axis formation, skeletal and muscle development, cell migration during early embryogenesis, as well as apoptosis, cell proliferation, and modulation of cardiac development.

Uncharacterized Regulator of G protein Signaling (RGS) domain subfamily, child 4; These uncharacterized RGS-like domains consists largely of hypothetical proteins. 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 role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins play critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. RGS proteins regulate many aspects of embryonic development such as glial differentiation, embryonic axis formation, skeletal and muscle development, cell migration during early embryogenesis, as well as apoptosis, cell proliferation, and modulation of cardiac development. Several RGS proteins can fine-tune immune responses, while others play an important role in neuronal signal modulation. Some RGS proteins are the principal elements needed for proper vision.
