Summary: Predicted to enable acetylcholine binding activity and acetylcholine-gated cation-selective channel activity. Predicted to contribute to acetylcholine receptor activity. Involved in regulation of synaptic vesicle exocytosis. Acts upstream of or within response to nicotine. Located in dopaminergic synapse. Part of acetylcholine-gated channel complex. Is expressed in gut; lung; nervous system; and thymus. Human ortholog(s) of this gene implicated in lung cancer. Orthologous to human CHRNA5 (cholinergic receptor nicotinic alpha 5 subunit).

Deletion of the alpha5 subunit in mice markedly reduces the cellular response to nicotine and acetylcholine in the interpeduncular nucleus. Stimulation of alpha5-expressing IP neurons using optogenetics is aversive, but this effect requires priming by recent prior stimulation or exposure to nicotine. The smoking-associated variant of the alpha5 gene may increase the drive to smoke via loss of IP-mediated nicotine avers...

Observations in hemiparkinsonian mice suggest that the lack of alpha5* nicotinic receptors results in attenuated dopaminergic neurodegeneration and motor dysfunction in a 6-OHDA neurotoxin model of Parkinson's disease; suggests potential for alpha5 subunit-containing nicotinic receptors as a novel target in the treatment of Parkinson's disease.

The findings reveal a proaddiction adaptive response to chronic nicotine in which nitric oxide and SST are released by a specific CHRNA5-expressing neuronal population to provide retrograde inhibition of the habenula- interpeduncular nucleus circuit and thereby enhance the motivational properties of nicotine.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
