Generation DefinitionsDonating Investigator Greg Barsh, Stanford University Medical Center Description
Mice that are homozygous for this targeted allele appear weak, fail to feed and die within a few hours of birth from unspecified causes. Embryos exhibit a slightly foreshortened head and abnormal lens development. No Maf gene transcript is detected. Posterior lens cells from homozygotes fail to elongate. These cells display inappropriately high levels of DNA synthesis and express alpha A crystallin and all of the beta crystallin genes at dramatically reduced levels. Heterozygotes are phenotypically normal. The presence of lacZ in the targeted allele makes it possible to observe Maf expression characteristics.Development
A targeting vector containing neomycin resistance, lacZ and herpes simplex virus thymidine kinase genes was used to disrupt the single Maf exon. The targeting construct was designed to remove the carboxy-terminal 351 amino acids and 3kb of 3' untranslated sequence. The lacZ gene was fused to an amino-terminal portion of the Maf gene encoding 19 amino acids. The construct was electroporated into 129X1/SvJ x 129S1/Sv-derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. The resulting chimeric animals were backcrossed to C57BL/6J mice.

involves: 129S1/Sv * 129X1/SvJ * C57BL/6J
- mortality/aging
- complete neonatal lethality
- mice die within hours of birth (MGI Ref ID J:56583)

- at E15.5, the boundary between proliferating and non-proliferating cells is shifted anteriorly (MGI Ref ID J:56583)
- abnormal lens vesicle development
- small lens
- at E17.5, lens size is reduced by one half or less of wild-type (MGI Ref ID J:56583)
- craniofacial phenotype
- shortened head
- mice exhibit a fore-shortened head at birth (MGI Ref ID J:56583)

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
