Mutation detailsExon 4, encoding a significant portion of the sailyl motif L, was deleted upon Cre mediated deletion of the floxed region including the exon and a tk-neo cassette. Southern blot confirmed recombination and RT-PCR indicated that the truncated form of mRNA was produced in heterozygous and homozygous mutants. The mutant cDNA was found to be inactive. (J:91777)
