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   -!- 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   -!- SIMILARITY: Belongs to the ligand-gated ion channel (TC 1.A.9) family.
CC       Acetylcholine receptor (TC 1.A.9.1) subfamily. Beta-1/CHRNB1 sub-
CC       subfamily. {ECO:0000305}.
