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 permeable to sodiun ions. {ECO:0000250}.
CC -!- SUBUNIT: Neuronal AChR is composed of two different types of subunits:
CC alpha and beta. Beta-2 subunit can be combined to alpha-2, alpha-3 or
CC alpha-4 to give rise to functional receptors, complexes with beta-2 may
CC be heteropentamers. Alpha-2/4:beta-2 nAChR complexes are proposed to
CC exist in two subtypes: LS (low agonist sensitivity) with a (alpha-
CC 2/4)3:(beta-2)2 and HS (high agonist sensitivity) with a (alpha-
CC 2/4)2:(beta-2)3 stoichiometry; the subtypes differ in their subunit
CC binding interfaces which are involved in ligand binding. Interacts with
CC RIC3; which is required for proper folding and assembly. Interacts with
CC LYPD6. The heteropentamer alpha3-beta-2 interacts with alpha-
CC cconotoxins BuIA, MII, ImI, ImII, PnIA and GID (By similarity). The
CC heteropentamer alpha-4-beta-2 interacts with the alpha-conotoxins PnIA,
CC GID and MII (By similarity). {ECO:0000250,
CC ECO:0000250|UniProtKB:P12390, ECO:0000250|UniProtKB:P17787}.
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-2/CHRNB2 sub-
CC subfamily. {ECO:0000305}.
