Summaries for CHRM4 Gene

Entrez Gene Summary for CHRM4 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 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 clinical implications of this receptor are unknown; however, mouse studies link its function to adenylyl cyclase inhibition. [provided by RefSeq, Jul 2008]

GeneCards Summary for CHRM4 Gene

CHRM4 (Cholinergic Receptor Muscarinic 4) is a Protein Coding gene. Among its related pathways are Monoamine GPCRs and Peptide ligand-binding receptors. Gene Ontology (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 CHRM2.

UniProtKB/Swiss-Prot for CHRM4 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 inhibition of adenylate cyclase.

Tocris Summary for CHRM4 Gene

  • 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.
