Dsg3^bal

This mutation was identified as an insertion of a thymidine residue in exon 14. The insertion causes a frameshift that results in a premature stop codon 78 bp downstream of the insertion. Antibodies to both extracellular and intracellular epitopes failed to stain epithelium of homozygous mutant mice, suggesting that any protein that may be synthesized is not inserted into the plasma membrane and/or is rapidly degraded.
