The alpha-4 beta-2 nicotinic acetylcholine receptor (α4β2 nAChR) is a type of receptor in the nervous system that responds to the neurotransmitter acetylcholine as well as nicotine, a substance found in tobacco. It is a subtype of the nicotinic acetylcholine receptor family, which are ligand-gated ion channels playing crucial roles in neurotransmission.
