Protein Structure

UniProt Annotation

Function

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 permeable to sodiun ions. {ECO:0000269PubMed:22361591}.

Subcellular Localization

Cell junction, synapse, postsynaptic cell membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein.

Disease Associations

Epilepsy, nocturnal frontal lobe, 3 (ENFL3) [MIM:605375]: An autosomal dominant focal epilepsy characterized by nocturnal seizures with hyperkinetic automatisms and poorly organized stereotyped movements. {ECO:0000269PubMed:11062464, ECO:0000269PubMed:11104662}. Note=The disease is caused by mutations affecting the gene represented in this entry.
