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 {ECO:0000269|PubMed:27375219}.
CC -!- SUBUNIT: Pentamer of two alpha chains, and one each of the beta, delta,
CC and gamma (in immature muscle) or epsilon (in mature muscle) chains.
CC The muscle heteropentamer composed of alpha-1, beta-1, delta, epsilon
CC subunits interacts with the alpha-conotoxin ImII (PubMed:15609996).
CC {ECO:0000269|PubMed:15609996}.
CC -!- SUBCELLULAR LOCATION: Postsynaptic cell membrane; Multi-pass membrane
CC protein. Cell membrane; Multi-pass membrane protein.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q07001-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q07001-2; Sequence=VSP_046423;
CC -!- DISEASE: Multiple pterygium syndrome, lethal type (LMPS) [MIM:253290]:
CC Multiple pterygia are found infrequently in children with
CC arthrogryposis and in fetuses with fetal akinesia syndrome. In lethal
CC multiple pterygium syndrome there is intrauterine growth retardation,
CC multiple pterygia, and flexion contractures causing severe
CC arthrogryposis and fetal akinesia. Subcutaneous edema can be severe,
CC causing fetal hydrops with cystic hygroma and lung hypoplasia.
CC Oligohydramnios and facial anomalies are frequent.
CC {ECO:0000269|PubMed:18252226}. Note=The disease is caused by variants
CC affecting the gene represented in this entry.
CC -!- DISEASE: Myasthenic syndrome, congenital, 3A, slow-channel (CMS3A)
CC [MIM:616321]: A form of congenital myasthenic syndrome, a group of
CC disorders characterized by failure of neuromuscular transmission,
CC including pre-synaptic, synaptic, and post-synaptic disorders that are
CC not of autoimmune origin. Clinical features are easy fatigability and
CC muscle weakness affecting the axial and limb muscles (with hypotonia in
CC early-onset forms), the ocular muscles (leading to ptosis and
CC ophthalmoplegia), and the facial and bulbar musculature (affecting
CC sucking and swallowing, and leading to dysphonia). The symptoms
CC fluctuate and worsen with physical effort. CMS3A is a slow-channel
CC myasthenic syndrome. It is caused by kinetic abnormalities of the AChR,
CC resulting in prolonged AChR channel opening episodes, prolonged
CC endplate currents, and depolarization block. This is associated with
CC calcium overload, which may contribute to subsequent degeneration of
CC the endplate and postsynaptic membrane. {ECO:0000269|PubMed:11782989}.
CC Note=The disease is caused by variants affecting the gene represented
CC in this entry.
CC -!- DISEASE: Myasthenic syndrome, congenital, 3B, fast-channel (CMS3B)
CC [MIM:616322]: A form of congenital myasthenic syndrome, a group of
CC disorders characterized by failure of neuromuscular transmission,
CC including pre-synaptic, synaptic, and post-synaptic disorders that are
CC not of autoimmune origin. Clinical features are easy fatigability and
CC muscle weakness affecting the axial and limb muscles (with hypotonia in
CC early-onset forms), the ocular muscles (leading to ptosis and
CC ophthalmoplegia), and the facial and bulbar musculature (affecting
CC sucking and swallowing, and leading to dysphonia). The symptoms
CC fluctuate and worsen with physical effort. CMS3B is a fast-channel
CC myasthenic syndrome. It is caused by kinetic abnormalities of the AChR,
CC resulting in brief opening and activity of the channel, with a rapid
CC decay in endplate current, failure to achieve threshold depolarization
CC of the endplate and consequent failure to fire an action potential.
CC {ECO:0000269|PubMed:11435464, ECO:0000269|PubMed:12499478,
CC ECO:0000269|PubMed:18398509}. Note=The disease is caused by variants
CC affecting the gene represented in this entry.
CC -!- DISEASE: Myasthenic syndrome, congenital, 3C, associated with
CC acetylcholine receptor deficiency (CMS3C) [MIM:616323]: A form of
CC congenital myasthenic syndrome, a group of disorders characterized by
CC failure of neuromuscular transmission, including pre-synaptic,
CC synaptic, and post-synaptic disorders that are not of autoimmune
CC origin. Clinical features are easy fatigability and muscle weakness
CC affecting the axial and limb muscles (with hypotonia in early-onset
CC forms), the ocular muscles (leading to ptosis and ophthalmoplegia), and
CC the facial and bulbar musculature (affecting sucking and swallowing,
CC and leading to dysphonia). The symptoms fluctuate and worsen with
CC physical effort. CMS3C is an autosomal recessive disorder of
CC postsynaptic neuromuscular transmission, due to deficiency of AChR at
CC the endplate that results in low amplitude of the miniature endplate
CC potential and current. {ECO:0000269|PubMed:16916845,
CC ECO:0000269|PubMed:18398509}. Note=The disease is caused by variants
CC affecting the gene represented in this entry.
CC -!- SIMILARITY: Belongs to the ligand-gated ion channel (TC 1.A.9) family.
CC Acetylcholine receptor (TC 1.A.9.1) subfamily. Delta/CHRND sub-
CC subfamily. {ECO:0000305}.
