WebC. G protein-coupled receptors (GPCRs) are the most diverse type of cell receptor. D. Intracellular receptors can be found in the cytoplasm or nucleus. D. Intracellular receptors can be found in the cytoplasm or nucleus. The cholera toxin does not allow GTP to be hydrolyzed to GDP. What effects would you expect to see in the cell? G protein-coupled receptor kinases (GPCRKs, GRKs) are a family of protein kinases within the AGC (protein kinase A, protein kinase G, protein kinase C) group of kinases. Like all AGC kinases, GRKs use ATP to add phosphate to Serine and Threonine residues in specific locations of target proteins. In … See more GRKs reside normally in an inactive state, but their kinase activity is stimulated by binding to a ligand-activated GPCR (rather than by regulatory phosphorylation as is common in other AGC kinases). Because there are only … See more X-ray crystal structures have been obtained for several GRKs (GRK1, GRK2, GRK4, GRK5 and GRK6), alone or bound to ligands. Overall, GRKs share sequence homology and domain organization in which the central protein kinase catalytic domain is preceded … See more • Downregulation and upregulation • Desensitization • G protein-coupled receptor See more GRK1 is involved with rhodopsin phosphorylation and deactivation in vision, together with arrestin-1, also known as S-antigen. Defects in GRK1 result in Oguchi stationary night blindness See more GRKs also phosphorylate non-GPCR substrates. GRK2 and GRK5 can phosphorylate some tyrosine kinase receptors, including … See more • Ma L, Gao J, Chen X (2005). "G Protein-Coupled Receptor Kinases". In Devi LA (ed.).
