功能After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.
疾病相关The muscle AChR is the major target antigen in the autoimmune disease myasthenia gravis. Myasthenia gravis is characterized by sporadic muscular fatigability and weakness, occurring chiefly in muscles innervated by cranial nerves, and characteristically improved by cholinesterase-inhibiting drugs. Myasthenic syndrome, congenital, 4A, slow-channel Myasthenic syndrome, congenital, 4B, fast-channel Myasthenic syndrome, congenital, 4C, associated with acetylcholine receptor deficiency
