Definitions related to adrenergic receptor:
-
A family of G protein-coupled receptors that bind catecholamines and play a role in the stimulation of the sympathetic nervous system.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Family of G protein coupled receptors sensitive to epinephrine, norepinephrine, and their analogs, found in smooth and cardiac muscle, autonomic ganglia, brain, and elsewhere.CRISP ThesaurusNational Institutes of Health, 2006
-
(receptors, adrenergic) Cell-surface proteins that bind epinephrine and/or norepinephrine with high affinity and trigger intracellular changes. The two major classes of adrenergic receptors, alpha and beta, were originally discriminated based on their cellular actions but now are distinguished by their relative affinity for characteristic synthetic ligands. Adrenergic receptors may also be classified according to the subtypes of G-proteins with which they bind; this scheme does not respect the alpha-beta distinction.NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
