G-protein Coupled Receptor Dimerization
A growing body of evidence suggests that GPCRs exist and function as dimers or higher oligomers. The evidence for GPCR dimerization comes from biochemical, biophysical and functional studies. In addition, researchers have shown the occurrence of heterodimerization between different members of the GPCR family. Two receptors can interact with each other to make a dimer through their extracellular...
متن کاملG protein-coupled receptor kinases.
G protein-coupled receptor kinases (GRKs) constitute a family of six mammalian serine/threonine protein kinases that phosphorylate agonist-bound, or activated, G protein-coupled receptors (GPCRs) as their primary substrates. GRK-mediated receptor phosphorylation rapidly initiates profound impairment of receptor signaling, or desensitization. This review focuses on the regulation of GRK activity...
متن کاملToxicology G Protein - Coupled Receptor Kinases
The importance of G protein-coupled receptor (GPCR) kinases (GRKs) as regulators of GPCR signaling has been widely recognized. In humans, GRKs constitute a family of seven protein kinases involved in the phosphorylation and desensitization of agonist-activated GPCRs in many physiological processes. The GPCR desensitization process is initiated by GRKs, but involves several subsequent steps incl...
متن کاملG protein-coupled receptor-associated sorting protein 1 regulates the postendocytic sorting of seven-transmembrane-spanning G protein-coupled receptors.
The largest superfamily of membrane proteins that translate extracellular signals into intracellular messages are the 7-transmembrane-spanning (7TM) G protein-coupled receptors (GPCR). One of the ways in which their activity is controlled is by the process of desensitization and endocytosis, whereby agonist-activated receptors are rapidly and often reversibly silenced through removal from the c...
متن کاملThe G protein-coupled receptor-associated protein 1 (GASP-1) regulates rimonabant-induced downregulation of GPR55
Background The G protein-coupled receptor 55 (GPR55) has recently been suggested to be responsible for those cannabinoid responses that could not be attributed to either the cannabinoid 1 (CB1) or cannabinoid 2 (CB2) receptor. Several potent GPR55 agonists were identified such as lysophosphatidylinositol (LPI) and several synthetic cannabinoids: One of these is rimonabant (SR141716A), an antago...
