Beta Adrenergic Receptor Written by NCI Thesaurus v.07.09d   

Definition of Beta Adrenergic Receptor Expressed by Beta Adrenergic receptor Genes in effector tissues innervated by postganglionic sympathetic adrenergic fibers, Beta Adrenergic Receptors are one of two major classes of adrenergic receptors (alpha and beta) based on their reactions to norepinephrine and epinephrine, on cellular effects of receptor activation, and on relative affinities and reactions to synthetic blocking or stimulating agents. Beta-adrenergic receptors respond to blocking agents such as propranolol and to activating agents such as isoproterenol. Beta-1 type receptors mediate lipolysis and increase cardiac rate and force of contraction -- beta-2 type receptor activation promotes bronchial and vascular smooth muscle relaxation. When coupled to adenylate cyclase through Gs protein, Beta Adrenergic receptor stimulation results in increased intracellular cyclic AMP. (NCI) Beta Adrenergic Receptor is from the group G Protein-Coupled Receptor Other Names for Beta Adrenergic Receptor Beta Adrenergic Receptor Source NCI Thesaurus License
