CHRNA10

Neuronal acetylcholine receptor subunit alpha-10, also known as nAChRα10 and cholinergic receptor nicotinic alpha 10, is a protein that in humans is encoded by the CHRNA10 gene.^[5] The protein encoded by this gene is a subunit of certain nicotinic acetylcholine receptors (nAchR).

This nAchR subunit is required for the normal function of the olivocochlear system which is part of the auditory system.^[6] 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.^[7]

α10 subunit-containing receptors are notably blocked by nicotine. The role of this antagonism in the effects of tobacco are unknown.
