Wt1^tm1.1Jak

The neomycin cassette was removed from the Wt1tm1Jak allele via cre mediated recombination to create the Wttm1.1Jak allele. This resulted in the deletion of the mammalian specific alternatively spliced exon 5, which encodes a 17 amino acid sequence known to interact with the transcription factor Pawr. (J:76780)
