CHRNA5 (Neuronal acetylcholine receptor subunit alpha-5) is a gene. In the public catalogues the evidence so far is association rather than a proven role. Tied to Lung cancer. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

Component of neuronal acetylcholine receptors (nAChRs) that function as pentameric, ligand-gated cation channels with high calcium permeability among other activities. nAChRs are excitatory neurotrasnmitter receptors formed by a collection of nAChR subunits known to mediate synaptic transmission in the nervous system and the neuromuscular junction. Each nAchR subunit confers differential attributes to channel properties, including activation, deactivation and desensitisation kinetics, pH sensitivity, cation permeability, and binding to allosteric modulators. Has an accessory rather than functional role and is only able to form functional nAChRs when co-assembled with another beta subunit. Participates in pentameric assemblies along with CHRNA3, CHRNA4, CHRNB2 and CHRNB4. Increases receptor sensitivity to acetylcholine and nicotine when associated with CHRNA4 and CHRNB2. Plays a role in nicotine addiction. Location: Synaptic cell membrane; Cell membrane (UniProt). Locus 15q25.1 (HGNC).
