WebThe G protein-coupled receptor kinases (GRKs) are protein kinases that phosphorylate only active GPCRs. G-protein-coupled receptor kinases (GRKs) are key modulators of G-protein-coupled receptor (GPCR) signaling. They constitute a family of seven mammalian serine-threonine protein kinases that phosphorylate agonist-bound receptor. WebWhereas phospholipase C (PLC) β is activated by Gα q and Gβγ, novel PLC isoforms are regulated by both heterotrimeric and Ras-superfamily G-proteins. An Arabidopsis protein has been discovered containing both GPCR and RGS domains within the same protein.

WebMany cell surface receptors, including G protein-coupled receptors and receptor tyrosine kinases, activate the PLC enzyme. PLC uses hydrolysis of the membrane phospholipid PIP 2 to form IP 3 and diacylglycerol (DAG), two classic secondary messengers. DAG attaches to the plasma membrane and recruits protein kinase C (PKC). WebApr 27, 2010 · Receptor activation leads to phospholipase C (PLC) activation, which cleaves phosphatidylinositol 4,5-bisphosphate (PIP 2) into IP 3 and diacylglycerol (DAG).
