NMR structures of the second transmembrane domain of the neuronal acetylcholine receptor beta 2 subunit
Disease
[ACHB2_HUMAN] Defects in CHRNB2 are the cause of nocturnal frontal lobe epilepsy type 3 (ENFL3) [MIM:605375]. ENFL3 is an autosomal dominant epilepsy characterized by nocturnal seizures with hyperkinetic automatisms and poorly organized stereotyped movements.[1][2]
Function
[ACHB2_HUMAN] 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 permeable to sodiun ions.[3]
