nAChRB4 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. Belongs to the ligand-gated ion channel (TC 1.A.9) family. Acetylcholine receptor (TC 1.A.9.1) subfamily. Beta-4/CHRNB4 sub-subfamily. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
