Gene: CHRNA1 (cholinergic receptor nicotinic alpha 1 subunit) Homo sapiens
Symbol: CHRNA1
Name: cholinergic receptor nicotinic alpha 1 subunit
Description: Exhibits acetylcholine-gated cation-selective channel activity. Predicted to contribute to acetylcholine binding activity and acetylcholine receptor activity. Involved in several processes, including muscle cell cellular homeostasis; neuronal action potential; and skeletal muscle tissue growth. Localizes to cell surface; neuromuscular junction; and plasma membrane. Implicated in congenital myasthenic syndrome 1A and congenital myasthenic syndrome 1B.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: acetylcholine receptor subunit alpha; acetylcholine receptor, nicotinic, alpha 1 (muscle); ACHRA; ACHRD; cholinergic receptor, nicotinic alpha 1; cholinergic receptor, nicotinic, alpha 1 (muscle); cholinergic receptor, nicotinic, alpha polypeptide 1 (muscle); CHRNA; CMS1A; CMS1B; CMS2A; FCCMS; muscle nicotinic acetylcholine receptor; nicotinic acetylcholine receptor alpha subunit; nicotinic cholinergic receptor alpha 1; SCCMS
