Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. This receptor binds epinephrine and norepinephrine with approximately equal affinity (PubMed:18594507). In dorsal pons neurons, involved in the regulation of sleep/wake behaviors (By similarity). Colocalizes with RAPGEF2 at the plasma membrane. Found in the Golgi upon GOPC overexpression (By similarity). Homologous desensitization of the receptor is mediated by its phosphorylation by beta-adrenergic receptor kinase. Belongs to the G-protein coupled receptor 1 family. Adrenergic receptor subfamily. ADRB1 sub-subfamily.
