General description

Cholinergic receptor nicotinic α1 subunit (CHRNA1) is the a subunit of nicotinic acetylcholine receptors. The protein is expressed at neuromuscular junctions. The gene encoding it is localized on human chromosome 2q31.1.

Nicotinic acetylcholine receptors (AChR) are members of a gene superfamily of ligand-gated ion channels, which includes the homologuous γ-aminobutyric acid type A (GABAA) receptors, glycine receptors and 5-HT3 serotonin receptors, but not the structurally dissimilar ligand-gated ion channels comprising the glutamate or ATP receptors. It is likely that all receptors in the AChR superfamily are comprised of five homologous subunits oriented around a central ion channel.


Recognizes an epitope with the sequence 371-386 of the α1 subunit of muscle nicotinic acetylcholine receptor. Binds to native and denatured α1 subunit of the nicotinic acetylcholine receptor.


denatured nicotinic acetylcholine receptors from the electric eel Electrophorus.

Biochem/physiol Actions

Cholinergic receptor nicotinic α1 subunit (CHRNA1) has a role in channel gating. Mutations in the gene have been associated with congenital myasthenic syndromes (CMS).

Nicotinic acetylcholine receptors (AChR) were first characterized in the skeletal muscles and their structural properties were initially characterized in using AChR′s from the homologous electric organ tissue of the Torpedo rays. The functional and structural characterization of neuronal AChR′s developed later due to their lower concentrations in more heterogenous tissues. AChR′s are now being associated with a growing number of diseases.
