Strain Name:

STOCK Gata4tm2(Gata4)Wtp/Mmjax


Cryopreserved - Ready for recovery     Available at the JAX MMRRC

Common Names: Gata4flap;    
Please refer to the Mutant Mouse Regional Resource Center (MMRRC) for information about STOCK Gata4tm2(Gata4)Wtp/Mmjax MMRRC Stock Number 032883.
These knockin mutant mice possess a floxed GATA4 cDNA with a transcriptional stop cassette followed by an alkaline phosphatase cDNA; cre-mediated excision activates AP expression. This mutant mouse strain may be useful in studies of cell lineage tracing in the developing and adult heart.


The genotypes of the animals provided may not reflect those discussed in the strain description or the mating scheme utilized by The Jackson Laboratory prior to cryopreservation. Please inquire for possible genotypes for this specific strain.

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.

Heterozygote: Normal

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.

Genes & Alleles

Gene & Allele Information provided by MGI

Allele Symbol Gata4tm2(Gata4)Wtp
Allele Name targeted mutation 2, William T Pu
Allele Type Targeted
Common Name(s) Gata4flap;
Mutation Made By William Pu,   Children's Hospital Boston, Harvard MS
Strain of Origin129S6/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.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
