RN [2] {ECO:0000313|Ensembl:ENSP00000490365.1} RP IDENTIFICATION. RG Ensembl; RL Submitted (NOV-2023) to UniProtKB. 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. The CC channel is blocked by alpha-bungarotoxin. CC {ECO:0000256|ARBA:ARBA00037502}. CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|ARBA:ARBA00004651}; CC Multi-pass membrane protein {ECO:0000256|ARBA:ARBA00004651}.
