Neuronal acetylcholine receptor subunit alpha-3, also known as nAChRα3, is a
protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, res ...
that in humans is encoded by the ''CHRNA3''
gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b ...

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.
