ADRENERGIC RECEPTORS
adrenergic receptors: translation
Receptors for noradrenaline and adrenaline. All are seven membrane spanning G-protein coupled receptors linked variously either to adenylate cyclase or phosphoinositide second messenger pathways. Three subgroups are usually recognized, the b -adrenergic receptors linked to Gs, the a 1 linked to Gi, and the a 2 linked to Gq. The b-adrenegic receptor gene is unusual in having no introns.
