This gene has 5 transcripts (splice variants), 198 orthologues, 45 paralogues and is associated with 3 phenotypes. Biased expression in brain (RPKM 9.5), adrenal (RPKM 0.7) and 1 other tissue.

Summary

Neuronal acetylcholine receptors are homo- or heteropentameric complexes composed of homologous alpha and beta subunits. They belong to a superfamily of ligand-gated ion channels which allow the flow of sodium and potassium across the plasma membrane in response to ligands such as acetylcholine and nicotine. This gene encodes one of several beta subunits. Mutations in this gene are associated with autosomal dominant nocturnal frontal lobe epilepsy. [provided by RefSeq, Jul 2008]
