Pleiotropic role for GRKs and β-arrestins in receptor regulation


Journal Article

G protein-coupled receptor kinases and arrestin proteins are well-characterized mediators of agonist-dependent G protein-coupled receptor desensitization. These proteins are now shown to play a dual role in receptor regulation by mediating both receptor uncoupling and sequestration, a process important for receptor resensitization. β-Arrestins bound to phosphorylated β2-adrenergic and angiotensin II type 1A receptors act as intracellular trafficking molecules specifically targeting these receptors for dynamin-dependent clathrin-coated vesicle-mediated sequestration.
