Chrm3 - cholinergic receptor, muscarinic 3

Enables several functions, including G protein-coupled acetylcholine receptor activity; G protein-coupled acetylcholine receptor binding activity; and acetylcholine binding activity. Involved in G protein-coupled acetylcholine receptor signaling pathway; negative regulation of heart rate by acetylcholine; and positive regulation of vascular associated smooth muscle contraction. Located in several cellular components, including asymmetric synapse; axon terminus; and dendrite. Is integral component of plasma membrane. Is active in glutamatergic synapse. Is integral component of postsynaptic density membrane and integral component of presynaptic membrane. 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, Apr 2022]
