title: Insulin action under arrestin.
abstract: Insulin signaling is key to the etiology of metabolic syndrome. Recent work (Luan et al., 2009) uncovers a role for beta-arrestin, previously known to control GPCR desensitization, in insulin signaling. In mouse models, beta-arrestin-2 controls whole-body insulin action by regulating assembly of a complex containing insulin receptor, c-Src, and Akt.
