Regulator of G protein signaling (RGS) domain found in the RGS6 protein; The RGS (Regulator of G-protein Signaling) domain is an essential part of the RGS6 protein, a member of R7 subfamily of the RGS protein family. RGS is a diverse group of multifunctional proteins that regulate cellular signaling events downstream of G-protein coupled receptors (GPCRs). Other members of the R7 subfamily (Neuronal RGS) include: RGS7, RGS9, and RGS11, all of which are expressed predominantly in the nervous system, form an obligatory complex with G-beta-5, and play important roles in the regulation of crucial neuronal processes such as vision and motor control. Additionally they have been implicated in many neurological conditions such as anxiety, schizophrenia, and drug dependence. RGS6 exists in multiple splice isoforms with identical RGS domains, but possess complete or incomplete GGL domains and distinct N- and C-terminal domains. RGS6 interacts with SCG10, a neuronal growth-associated protein and therefore regulates neuronal differentiation. Another RGS6-binding protein is DMAP1, a component of the Dnmt1 complex involved in repression of newly replicated genes. Mutations of a critical residue required for interaction of RGS6 protein with G proteins did not affect the ability of RGS6 to interact with both SCG10 and DMAP1. 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.

RGS9 exists in two splice isoforms: RGS9-1 which regulates phototransduction in rods and cones and RGS9-2 which regulates dopamine and opioid signaling in the basal ganglia. In addition, RGS9 was found to bind many other proteins outside of G protein signaling pathways including: mu-opioid receptor, beta-arrestin, alpha-actinin-2, NMDAR, polycystin, spinophilin, and guanylyl cyclase, among others.

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.

Regulator of G protein signaling (RGS) domain found in the RGS19 protein; The RGS (Regulator of G-protein Signaling) domain is an essential part of the RGS19 protein (also known as GAIP), 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 RGS domains, which accelerate GTPase activity of the alpha subunit by hydrolysis of GTP to GDP, resulting in a reassociation of the alpha-subunit with the beta-gamma-dimer and an 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 includes RGS17, RGS20, and its splice variant Ret-RGS. RGS19 participates in regulation of dopamine receptor D2R and D3R, as well as beta-adrenergic receptors .

Regulator of G protein signaling (RGS) domain found in the FLBA (Fluffy Low BrlA) protein; The RGS (Regulator of G-protein Signaling) domain is an essential part of the FLBA (Fluffy Low BrlA) protein.

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 play a critical regulatory role as GTPase activating proteins (GAPs) of the heterotrimeric G-protein G-alpha-subunits. Deactivation of the G-protein signaling controlled by the RGS domain accelerates the GTPase activity of the alpha subunit by hydrolysis of GTP to GDP which results in 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. The RGS domain of the FLBA protein antagonizes G protein signaling to block proliferation and allow development. It is required for control of mycelial proliferation and activation of asexual sporulation in yeast.

Uncharacterized Regulator of G protein Signaling (RGS) domain subfamily, child 1; 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. As a major G-protein regulator, the RGS domain containing proteins that are involved in many crucial cellular processes. 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.

DEP (Dishevelled, Egl-10, and Pleckstrin) domain 1 found in P-Rex-like proteins. The P-Rex family is the guanine-nucleotide exchange factor (GEF) for the small GTPase Rac that contains an N-terminal RhoGEF domain, two DEP and PDZ domains. Rac-GEF activity is stimulated by phosphatidylinositol (3,4,5)-trisphosphate (PtdIns(3,4,5)P3), a lipid second messenger, and by the G beta-gamma subunits of heterotrimeric G proteins. The DEP domains are not involved in mediating these stimuli, but may be of importance for basal and stimulated levels Rac-GEF activity.

DEP (Dishevelled, Egl-10, and Pleckstrin) domain found in fungal RhoGAP (GTPase-activator protein) Rgd2-like proteins. Rgd2-like proteins share a common domain architecture, containing, beside the RhoGAP domain, a DEP and a FCH (Fes/CIP4 homology) domain. Yeast Rgd2 is a GAP protein for Cdc42 and Rho5.

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.
