Zfpm2^tm1Sho

The gene was disrupted by replacement of sequences encoding all of the zinc finger motifs with a floxed neomycin-cytidine deaminase cassette. The floxed cassette was removed by crossing mutant animals to a cre deleter strain. Homozygous mutant embryos were detected by Southern blot analysis up to day E15.5. RNase protection assay showed an absence of Zfpm2 mRNA in hearts of E12.5 homozygous mutant embryos. (J:62879)
