MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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]
PHENOTYPE: Homozygotes for targeted null mutations have impaired responses to nicotine, but show improved passive avoidance behavior. With age, mutants show more neurodegeneration and alterations of the visual system, with decreased cortical visual acuity. [provided by MGI curators]
