Biochem/physiol Actions

The protein encoded by CHRNA7 displays marked permeability to calcium ions and is a major component of brain nicotinic receptors that are blocked by, and highly sensitive to, alpha-bungarotoxin. Once this receptor binds acetylcholine, it undergoes an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane. This gene is located in a region identified as a major susceptibility locus for juvenile myoclonic epilepsy and a chromosomal location involved in the genetic transmission of schizophrenia.

General description

Neuronal acetylcholine receptor subunit α-7 (CHRNA7 or NACHRA7) is a subunit of a member of the nicotinic acetylcholine receptor family. These proteins are hetero-pentamers composed of homologous subunits. Upon acetylcholine binding the receptor undergoes a conformational change resulting in an open ion channel. CHRNA7 is found highly expressed in the hippocampus localized to GABAergic neurons.
