a GPCR-coupled 7 transmembrane receptor that binds epinephrine and norepinephrine with approximately equal affinity. Mediates the catecholamine-induced activation of adenylate cyclase through the action of G proteins. Interacts with PIST and PSD-95. Localized at the plasma membrane and in the Golgi upon PIST overexpression. Homologous desensitization of the receptor is mediated by its phosphorylation by beta-adrenergic receptor kinase. Note: This description may include information from UniProtKB.
