phenotypes
All mutations/alleles(11) : Gene trapped(8) Targeted(3)
Incidental mutations (data from Mutagenetix , APF )
 
Mice homozygous for a knock-in allele lack all tyrosine residues in the beta subunit intracellular loop, display reduced and simplified neuromuscular junctions, and show defective acetylcholine receptor clustering and anchoring at synapses.
