Regulator of G protein signaling - Wikipedia RGS proteins markedly reduce the lifespan of GTP-bound α-subunits by stabilising the G protein transition state Whereas receptors stimulate GTP binding, RGS proteins stimulate GTP hydrolysis RGS proteins have been conserved in evolution
A Global Map of G Protein Signaling Regulation by RGS Proteins To understand the principles governing the selectivity of Gα regulation by RGS, we examine the catalytic activity of all canonical human RGS proteins and their selectivity for a complete set of Gα substrates using real-time kinetic measurements in living cells
Roles for Regulator of G Protein Signaling Proteins in Synaptic . . . The regulator of G protein signaling (RGS) family of proteins serves critical roles in G protein-coupled receptor (GPCR) and heterotrimeric G protein signal transduction RGS proteins are best understood as negative regulators of GPCR G protein signaling
Regulators of G protein Signaling (RGS) proteins | Other protein . . . Regulator of G protein Signaling, or RGS, proteins serve an important regulatory role in signaling mediated by G protein-coupled receptors (GPCRs) They all share a common RGS domain that directly interacts with active, GTP-bound Gα subunits of heterotrimeric G proteins
Regulator of G-protein signaling (RGS) proteins as drug targets . . . In this review, we provide a brief overview of the discovery of RGS proteins and of the gradual and continuing discovery of their roles in disease states, focusing particularly on cancer and neurological disorders
RGS Protein Domain - Cell Signaling Technology The RGS (Regulator of G protein Signaling) domain found in over 20 human proteins is approximately 120 amino acids in length RGS domains act allosterically by stabilizing the transition intermediate of the GTP binding pocket of heterotrimeric G protein α subunits
