Summary: Enables acetylcholine binding activity and acetylcholine-gated cation-selective channel activity. Predicted to be involved in several processes, including behavioral response to nicotine; cholinergic synaptic transmission; and regulation of synaptic vesicle exocytosis. Located in dendrite; neuronal cell body; and plasma membrane. Part of acetylcholine-gated channel complex. Human ortholog(s) of this gene implicated in lung cancer. Orthologous to human CHRNA5 (cholinergic receptor nicotinic alpha 5 subunit). [provided by Alliance of Genome Resources, Apr 2022]

Rats expressing the alpha5SNP consume more alcohol, and exhibit increased relapse to alcohol seeking after abstinence.
Title: Profound alteration in reward processing due to a human polymorphism in CHRNA5: a role in alcohol dependence and feeding behavior.
The alpha5SNP polymorphism is a major risk factor for nicotine intake at high doses and for relapse to nicotine seeking in rats, a dual effect that reflects the human condition. The results also suggest an important role for the IPN in the higher relapse to nicotine seeking observed in alpha5SNP rats.

This study provide evidence that through its contribution to cholinergic modulation of cholinergic modulation of neurons in the PFC, the alpha5 nAChR plays a specific role in the recovery of attention task performance following distraction.

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.
