Beta adrenergic receptor activation - Activation mechanism of the β2-adrenergic receptor
Adrenergic receptors respond to sympathetic stimulation and blood-borne epinephrine. Receptors are located on smooth muscle, cardiac pacemaker, myocardium and glands.
Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. Beta-3 is involved in the regulation of lipolysis and thermogenesis.
Beta 1- and beta 2-adrenergic receptor-mediated adenylate cyclase stimulation in
Adrenergic receptor. Adrenoceptors (ARs) are members of the G-protein–coupled receptor superfamily, interfacing between the sympathetic nervous system and the cardiovascular system, with integral roles in the rapid regulation of myocardial function.
Beta adrenergic receptor kinase (also referred to as βARK or BARK) is a serine/threonine intracellular kinase. It is activated by PKA and its target is the beta adrenergic receptor.
