NCIt definition : Beta-1 adrenergic receptor (477 aa, 51 kDa) is encoded by the human ADRB1 gene. This
protein plays a role in catecholamine-dependent G protein-coupled receptor signaling.;
NCIt note : Encoded by human ADRB1 Gene (GPCR1 Family), 477-aa 51-kDa conserved Beta-1-Adrenergic
Receptor is an integral membrane protein receptor for catecholamine epinephrine and
norepinephrine neurotransmitters that activates adenylate cyclase through G protein
action. ADRB1 phosphorylation by beta-adrenergic receptor kinase mediates receptor
desensitization. Agonist and antagonist drugs selective for beta-1 receptors have
important applications in clinical medicine.;
