CHRNG [ENSP00000374145]
 
cholinergic receptor, nicotinic, gamma; 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
CHRNA2 [ENSP00000240132]
 
cholinergic receptor, nicotinic, alpha 2 (neuronal); 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
