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 -!- CATALYTIC ACTIVITY:
CC Reaction=K(+)(in) = K(+)(out); Xref=Rhea:RHEA:29463, ChEBI:CHEBI:29103;
CC Evidence={ECO:0000250|UniProtKB:P13536};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Na(+)(in) = Na(+)(out); Xref=Rhea:RHEA:34963,
CC ChEBI:CHEBI:29101; Evidence={ECO:0000250|UniProtKB:P13536};
CC -!- SUBUNIT: Pentamer of two alpha chains, and one each of the beta, delta,
CC and gamma chains.
CC -!- SUBCELLULAR LOCATION: Postsynaptic cell membrane; Multi-pass membrane
CC protein. Cell membrane; Multi-pass membrane protein.
CC -!- PTM: Seems not to be glycosylated on Asn-158.
CC -!- SIMILARITY: Belongs to the ligand-gated ion channel (TC 1.A.9) family.
CC Acetylcholine receptor (TC 1.A.9.1) subfamily. Gamma/CHRNG sub-
CC subfamily. {ECO:0000305}.
