Generic protein structure example

Neuronal acetylcholine receptor subunit alpha-1, also known as nAChRα1, is a protein that in humans is encoded by the CHRNA1 gene.[1] The protein encoded by this gene is a subunit of certain nicotinic acetylcholine receptors (nAChR).

The muscle acetylcholine receptor consists of 5 subunits of 4 different types: 2 alpha isoforms and 1 each of beta, gamma, delta and epsilon subunits. The gamma sub-unit being only present in embryonic nAChR[2]. This gene encodes an alpha subunit that plays a role in acetylcholine binding/channel gating. Alternatively spliced transcript variants encoding different isoforms have been identified.[1]

Interactions

Cholinergic receptor, nicotinic, alpha 1 has been shown to interact with CHRND.[3][4]
