毒蕈碱胆碱能受体属于g蛋白偶联受体的一个大家族。这些受体的功能多样性由乙酰胆碱与这些受体的结合来定义，包括腺苷酸环化酶抑制、磷酸肌醇变性和钾通道介导等细胞反应毒蕈碱受体影响乙酰胆碱在中枢和外周神经系统的许多作用。胆碱能受体2介导心动过缓和心肌收缩力下降。已经描述了该基因的多个选择性剪接转录变体。[由RefSeq提供，2008年7月]
The muscarinic cholinergic receptors belong to a larger family of G protein-coupled receptors. The functional diversity of these receptors is defined by the binding of acetylcholine to these receptors and includes cellular responses such as adenylate cyclase inhibition, phosphoinositide degeneration, and potassium channel mediation. Muscarinic receptors influence many effects of acetylcholine in the central and peripheral nervous system. The muscarinic cholinergic receptor 2 is involved in mediation of bradycardia and a decrease in cardiac contractility. Multiple alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Jul 2008]
