Homozygotes: Mice homozygous for the targeted mutation are viable and fertile. Homozygous mutant mice show no overt phenotypic abnormalities. When used in conjunction with a Cre recombinase-expressing strain, this strain is useful in generating tissue-specific mutants of the floxed allele. Cre-mediated excision of Gata4 is coupled with alkaline phosphatase expression under the control of the endogenous Gata4 regulatory elements. This mutant mouse strain may be useful in studies of cell lineage tracing in the developing and adult heart.
A targeting vector containing a loxP-flanked Gata4 cDNA with a transcriptional stop cassette followed by an alkaline phosphatase cDNA and an FRT-flanked PGKneo cassette was inserted into the 5' UTR of the targeted gene. The construct was electroporated into 129S6/SvEvTac derived TC-1 embryonic stem (ES) cells. Chimeric animals were crossed to C57BL/6 and SJL mixed background Tg(ACTFLPe)9205Dym mice to remove the neomycin cassette. To remove the FLP transgene, mice were mated with outbred Black Swiss mice and then intercrossed to establish a homozygous colony. Upon arrival, mice were bred to C57BL/6J for at least 1 generation to establish the colony.

loxP-flanked Sequences: Test/Reporter
|Allele Name||targeted mutation 2, William T Pu|
|Mutation Made By||William Pu, Children's Hospital Boston, Harvard MS|
|Strain of Origin||129S6/SvEvTac|
|Expressed Gene||Gata4, GATA binding protein 4, mouse, laboratory|
|Molecular Note||Exon 2 was replaced with a floxed full-length Gata4 cDNA with a transcription STOP sequence followed by an alkaline phosphatase gene with a 3' frt site. An frt-flanked neo cassette used for selection purposes was removed by germ line, flp-mediated recombination. Cre mediated recombination is necessary to activate alkaline phospatase expression.
