CC -!- FUNCTION: After binding acetylcholine, the AChR responds by an
CC extensive change in conformation that affects all subunits and leads to
CC opening of an ion-conducting channel across the plasma membrane.
CC {ECO:0000256|ARBA:ARBA00003328}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|ARBA:ARBA00004651};
CC Multi-pass membrane protein {ECO:0000256|ARBA:ARBA00004651}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
