Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables G protein-coupled acetylcholine receptor activity. Involved in G protein-coupled receptor signaling pathway; ligand-gated ion channel signaling pathway; and positive regulation of insulin secretion. Acts upstream of or within cholinergic synaptic transmission; positive regulation of smooth muscle contraction; and saliva secretion. Is active in plasma membrane. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Used to study megacystis-microcolon-intestinal hypoperistalsis syndrome. Human ortholog(s) of this gene implicated in bladder disease; chronic obstructive pulmonary disease; prune belly syndrome; and pulmonary fibrosis. Orthologous to human CHRM3 (cholinergic receptor muscarinic 3).
