Previous GeneCards Identifiers for CHRM2 Gene
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]
GeneCards Summary for CHRM2 Gene
CHRM2 (Cholinergic Receptor Muscarinic 2) is a Protein Coding gene. Diseases associated with CHRM2 include Peripartum Cardiomyopathy and Bladder Neck Obstruction. Among its related pathways are Peptide ligand-binding receptors and Myometrial Relaxation and Contraction Pathways. GO annotations related to this gene include G-protein coupled receptor activity and G-protein coupled acetylcholine receptor activity. An important paralog of this gene is CHRM4.
UniProtKB/Swiss-Prot for CHRM2 Gene
The muscarinic acetylcholine receptor mediates various cellular responses, including inhibition of adenylate cyclase, breakdown of phosphoinositides and modulation of potassium channels through the action of G proteins. Primary transducing effect is adenylate cyclase inhibition. Signaling promotes phospholipase C activity, leading to the release of inositol trisphosphate (IP3); this then triggers calcium ion release into the cytosol.
Muscarinic receptors are widely distributed throughout the body and control distinct functions according to location and subtype (M1 - M5).They are predominantly expressed in the parasympathetic nervous system where they exert both inhibitory and excitatory effects.
