1 Beta-adrenergic receptors transduce catecholamine binding to activation of adenylylcyclase, a response counter-regulated by insulin. Catecholamines insulin Cricetulus griseus
2 Insulin stimulates tyrosine phosphorylation of Tyr 350/354, which abolishes the catecholamine response. Catecholamines insulin Cricetulus griseus
3 These data provide a biochemical link between the ability of insulin to counter-regulate catecholamine stimulation of cyclic AMP accumulation and the phosphorylation of the beta-adrenergic receptor, consequent biding of the adaptor molecule Grb2 and disruption of receptor-G-protein coupling. Catecholamines insulin Cricetulus griseus
