The α3β4 nicotinic acetylcholine receptor (nAChR) is a subtype of nicotinic receptor that is primarily composed of alpha 3 (α3) and beta 4 (β4) subunits. Nicotinic receptors are a type of neurotransmitter receptor that responds to the neurotransmitter acetylcholine (ACh) as well as other compounds, such as nicotine.
