nAChRB2 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. Defects in CHRNB2 are the cause of nocturnal frontal lobe epilepsy type 3 (ENFL3). ENFL3 is an autosomal dominant epilepsy characterized by nocturnal seizures with hyperkinetic automatisms and poorly organized stereotyped movements. Belongs to the ligand-gated ion channel (TC 1.A.9) family. Acetylcholine receptor (TC 1.A.9.1) subfamily. Beta- 2/CHRNB2 sub-subfamily. Note: This description may include information from UniProtKB.
