Neuronal acetylcholine receptor subunit alpha-3, also known as nAChRα3, is a protein that in humans is encoded by the CHRNA3 gene.^[5]^[6] The protein encoded by this gene is a subunit of certain nicotinic acetylcholine receptors (nAchR). Research with mecamylamine in animals has implicated alpha-3-containing nAChRs in the abusive and addictive properties of ethanol.
