Recombinase Activity

Comparison Matrix Gene Expression + Recombinase Activity

Homozygotes for targeted null mutations exhibit skin with epithelial hyperplasia, abnormal nuclei, premature lipid secretion, and abnormal keratohyaline granules. Mutants die within 40 hours of birth due to inability to clear their lungs of liquid.
