CC -!- FUNCTION: Upon acetylcholine binding, the AChR responds by an extensive
CC change in conformation that affects all subunits and leads to opening
CC of an ion-conducting channel across the plasma membrane.
CC {ECO:0000256|ARBA:ARBA00037634}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|ARBA:ARBA00004651};
