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};
CC Multi-pass membrane protein {ECO:0000256|ARBA:ARBA00004651}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}. Postsynaptic cell membrane
CC {ECO:0000256|ARBA:ARBA00034104}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00034104}. Synaptic cell membrane
CC {ECO:0000256|ARBA:ARBA00034099}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00034099}.
CC -!- SIMILARITY: Belongs to the ligand-gated ion channel (TC 1.A.9) family.
CC Acetylcholine receptor (TC 1.A.9.1) subfamily. Alpha-1/CHRNA1 sub-
CC subfamily. {ECO:0000256|ARBA:ARBA00038312}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
