WebIntroduction. β-Adrenergic receptors are G-protein coupled transmembrane proteins. Their main antianginal action lies in the intracellular part of the β-receptor that is coupled to the G-protein complex: G s (stimulatory) and G i (inhibitory). Agonists bind to the ligand site and stimulate the β-adrenergic receptors (β 1, β 2, and β 3 ...
