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.

When activated, the D1R also recruits the scaffolding protein β-arrestin, which promotes receptor desensitization and internalization, as well as additional downstream signaling pathways.

GPCRs become desensitized when exposed to their ligand for a long period of time. There are two recognized forms of desensitization: 1) homologous desensitization, in which the activated GPCR is downregulated; and 2) heterologous desensitization, wherein the activated GPCR causes downregulation of a different GPCR. The key reaction of this downregulation is the phosphorylation of the intracellular (or cytoplasmic) receptor domain by protein kinases. WebG-protein-coupled receptor kinases (GRK) contain a regulator of G-protein signaling (RGS)-like domain located at the N terminus (GRK-Nter) of their sequence. This domain …
