Arrestins were originally characterized as structural adaptor proteins which modulate the desensitization and trafficking of seven-membrane-spanning receptors. From these seminal observations a multitude of novel functions for this gene family have arisen. Here we review the recently identified roles for β-arrestin including its nuclear function and roles in development, cellular migration, and metastasis.
