These Bptf (bromodomain PHD finger transcription factor) mutant mice carry a loxP site flanked (floxed) exon 2 and may be useful in generating conditional mutations for studying chromatin remodeling during development.

Targeted (Conditional ready (e.g. floxed), No functional change) | Bptf | bromodomain PHD finger transcription factor |
These mice possess loxP sites on either side of exon 2 of the targeted gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When these mutant mice are bred to mice that express Cre recombinase, resulting offspring will have exon 2 deleted in the cre-expressing tissue(s). This mutant mouse strain may be useful in generating conditional mutations for studying chromatin remodeling during development.
A loxP site flanked targeting vector containing a neo cassette was utilized in the construction of this mutant. This selection cassette was inserted downstream of exon 2 of the targeted gene, and another loxP site was inserted upstream of exon 2. This construct was electroporated into 129S1/Sv-Oca2+ Tyr+ Kitl+ derived CJ7 embryonic stem (ES) cells. Correcting targeted ES cells that had successfully undergone Cre recombination and no longer retained the cassette but did retain the loxP-flanked exon 2 were injected in recipient blastocysts. The resulting chimeric mice were crossed to a Flp recombinase expressing strain (N10 on the C57BL/6NCr background) to delete the Neo cassette while retaining loxP sites flanking exon 2. The mice were backcrossed to wildtype C57BL/6NCr mice for 12 generations and no longer carry the Flp expressing transgene. Upon arrival at The Jackson Laboratory the mice were crossed to C57BL/6NJ once.

Strain of Origin | 129S1/Sv-Oca2+ Tyr+ Kitl+ |
Chromosome | 11 |
Molecular Note | A loxP site was inserted upstream of exon 2, and a frt-flanked neomycin cassette and a downstream loxP was inserted downstream of exon 2. Flpe expression removed the neomycin cassette leaving exon 2 floxed. |
When maintaining a live colony, these mice can be bred as homozygotes.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
