MGI Phenotype FUNCTION: This gene encodes an alpha subunit of the muscle-derived nicotinic acetylcholine receptor, a pentameric neurotransmitter receptor and member of the ligand-gated ion channel superfamily. The alpha subunit plays a role in substrate binding and channel gating. [provided by RefSeq, Nov 2012]
PHENOTYPE: Mice homozygous for a knock-out allele exhibit neonatal lethality, kyphosis, carpotosis, absent miniature and nerve-evoked endplant potential, increased motor neuron number, and abnormal neuromuscular synapse. [provided by MGI curators]
