Visual arrestin, betaarrestin1, and betaarrestin2 comprise a family of intracellular proteins that desensitize G protein-coupled receptors (GPCRs). In addition, betaarrestin1 and betaarrestin2 target(More)
beta-Arrestins bind agonist-activated G protein-coupled receptors (GPCRs) and mediate their desensitization and internalization. Although beta-arrestins dissociate from some receptors at the plasma(More)
Resensitization of G protein-coupled receptors (GPCRs) following agonist-mediated desensitization is a necessary step for maintaining physiological responsiveness. However, the molecular mechanisms(More)
