Target

Full Name
Cholinergic Receptor Nicotinic Alpha 5 Subunit
Introduction
Nicotinic acetylcholine receptors (nAChRs), such as CHRNA5, are members of a superfamily of ligand-gated ion channels that mediate fast signal transmission at synapses. The predicted 468-amino acid protein has a putative 22-amino acid signal peptide. The mature protein is 87% identical to rat alpha-5 protein. On Northern blots, alpha-5 was expressed in almost all neuronal and nonneuronal cells tested as 2 major transcripts of 2.7 and 2.1 kb, with additional mRNAs seen in 1 neuroblastoma cell line. The nAChRs are thought to be (hetero)pentamers composed of homologous subunits.

Alternative Names
Cholinergic Receptor, Nicotinic, Alpha 5 (Neuronal); Cholinergic Receptor, Neuronal Nicotinic, Alpha Polypeptide-5; Neuronal Nicotinic Acetylcholine Receptor, Alpha5 Subunit; Acetylcholine Receptor, Nicotinic, Alpha 5 (Neuronal); Cholinergic Receptor, Nicotinic, Alpha Polypeptide 5; Acetylcholine Receptor; Alpha 5 (Neuronal); Nicotinic; NACHRA5; LNCR2
Function
After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.
