Beta-arrestins: multifunctional cellular mediators.
Initially thought to play a role only in G-protein-coupled receptor desensitization, beta-arrestins are ascribed with new roles such as scaffolding and signaling proteins by their own right. This review explores the many functions of beta-arrestins, with an emphasis on their recently identified role as regulators of receptor signaling.
