WebJan 28, 2011 · GRK Phosphorylation of Receptors for β-Arrestin Recruitment GRK-phosphorylation of receptors is not sufficient for desensitization, but rather serves to create high affinity sites to promote the recruitment of the cytoplasmic accessory proteins, arrestins, and target the receptors for internalization via clathrin-coated pits. WebThe sequence of GRK2 fits strongly the consensus phosphorylation motif for proline-directed kinases, in which a Pro residue at the −1 position relative to the phosphorylation site is absolutely required along with a weak preference for Pro and other aliphatic residues at the −2 position.
