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] ,
