Chrm3 Gene Summary [Mouse]

Enables G protein-coupled acetylcholine receptor activity. Involved in ligand-gated ion channel signaling pathway; phospholipase C-activating G protein-coupled acetylcholine receptor 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). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Chrm3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
