This gene encodes beta-2-adrenergic receptor which is a member of the G protein-coupled receptor superfamily. This receptor is directly associated with one of its ultimate effectors, the class C L-type calcium channel Ca(V)1.2. This receptor-channel complex also contains a G protein, an adenylyl cyclase, cAMP-dependent kinase, and the counterbalancing phosphatase, PP2A. The assembly of the signaling complex provides a mechanism that ensures specific and rapid signaling by this G protein-coupled receptor. This gene is intronless. Different polymorphic forms, point mutations, and/or downregulation of this gene are associated with nocturnal asthma, obesity and type 2 diabetes. [provided by RefSeq, Jul 2008]

UniProtKB/Swiss-Prot for ADRB2 Gene
Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. The beta-2-adrenergic receptor binds epinephrine with an approximately 30-fold greater affinity than it does norepinephrine.
The adrenergic beta2 receptor (beta2-adrenoceptor) is a member of the adrenergic receptor group of G-protein-coupled receptors that also includes alpha1A, alpha1B, alpha1D, alpha2A, alpha2B, alpha2C, beta1 and beta3. They are located primarily in the CNS, heart, kidney and muscle.
