Neuronal acetylcholine receptor subunit alpha-10 also known as cholinergic receptor nicotinic alpha 10 is a protein that in humans is encoded by the CHRNA10 gene.[1] The protein encoded by this gene is a subunit of the nicotinic acetylcholine receptor (nAchR).

This nAchR subunit is required for the normal function of the olivocochlear system which is part of the auditory system.[2] Furthermore selective block of α9α10 nicotinic acetylcholine receptors by the conotoxin RgIA has been shown to be analgesic in an animal model of nerve injury pain.[3]
