MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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 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 1 is involved in mediation of vagally-induced bronchoconstriction and in the acid secretion of the gastrointestinal tract. The gene encoding this receptor is localized to 11q13. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygotes for targeted null mutations exhibit resistance to pilocarpine-induced seizures, selective memory deficits, elevated dopaminergic transmission in the striatum, and increased spontaneous and amphetamine-induced locomotion. [provided by MGI curators]
