1 Double mutation (i.e. S345A/S346A) within this motif abolishes insulin counterregulation of beta-adrenergic stimulation of cyclic AMP accumulation as well as insulin-stimulated sequestration. Cyclic AMP insulin Homo sapiens
2 Furthermore, expression of constitutively activated Akt (T308D/S473D) mimics insulin action on cyclic AMP responses and beta(2)-adrenergic receptor internalization. Cyclic AMP insulin Homo sapiens
3 Expression of the dominant-negative version of Akt (K179A/T308A/S473A), in contrast, abolishes both insulin counterregulation of the cyclic AMP response as well as insulin-stimulated sequestration of the beta(2)-adrenergic receptor. Cyclic AMP insulin Homo sapiens
