Summaries for CHRNA5 Gene

Entrez Gene Summary for CHRNA5 Gene

  • The protein encoded by this gene is a nicotinic acetylcholine receptor subunit and a member of a superfamily of ligand-gated ion channels that mediate fast signal transmission at synapses. These receptors are thought to be heteropentamers composed of separate but similar subunits. Defects in this gene have been linked to susceptibility to lung cancer type 2 (LNCR2).[provided by RefSeq, Jun 2010]

GeneCards Summary for CHRNA5 Gene

CHRNA5 (Cholinergic Receptor Nicotinic Alpha 5 Subunit) is a Protein Coding gene. Diseases associated with CHRNA5 include Smoking As A Quantitative Trait Locus 3 and Malignant Glioma. Among its related pathways are Transmission across Chemical Synapses and Postsynaptic nicotinic acetylcholine receptors. Gene Ontology (GO) annotations related to this gene include extracellular ligand-gated ion channel activity and ligand-gated ion channel activity. An important paralog of this gene is CHRNB3.

UniProtKB/Swiss-Prot for CHRNA5 Gene

  • After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.
