β-Arrestin 1 down-regulation after insulin treatment is associated with supersensitization of β2 adrenergic receptor Gαs signaling in 3T3-L1 adipocytes

β-Arrestin 1 is required for internalization and mitogen-activated protein (MAP) kinase activation by the β2 adrenergic receptor (β2AR). Our previous studies have shown that chronic insulin treatment down-regulates cellular β-arrestin 1 levels, leading to a marked impairment in G protein-coupled rec...
