These mice possess loxP sites flanking exons 3 through 6 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. Histological analysis of brains from homozygotes reveals slightly wider CA1 and CA3 regions and a split in CA2 region in the hippocampus. When these mutant mice are bred to mice that express Cre recombinase, resulting offspring will have exons 3 through 6 deleted in the cre-expressing tissue(s).Development
A loxP site flanked targeting vector containing PGKneo was utilized in the construction of this mutant.This selection cassette was inserted into intron 2 of the targeted gene, and another loxP site was inserted into intro 6. This construct was electroporated into 129S6/SvEvTac derived TC-1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric animals were crossed to 129S6/SvEvTac mice for 9 generations. Upon arrival at The Jackson Laboratory, mice were bred to 129S1/SvImJ mice (Stock No. 002448) for at least one generation to establish the colony.

| Molecular Note | A floxed PGK-neo cassette was inserted into intron 2 and a third loxP site was introduced into intron 6 via homologous recombination. This allele is hypomorphic, because of disruption of transcription or splicing by the insertion of a phosphoglycerate kinase neomycin cassette from the targeting vector into the second intron (J:82268).

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.Ordering Information
