Strain Information

Type Congenic; Mutant Strain; Targeted Mutation; Additional information on Genetically Engineered Mutant Mice. Mating System Heterozygote x +/+ sibling         (Female x Male) Species laboratory mouse Generation N10+N1F1N1F7 (13-OCT-08)   Donating Investigator Morris Birnbaum,   Un of Pennsylvania Schl of Medicine

Description
Mice that are homozygous for the targeted mutation are viable and do not display any gross behavioral abnormalities. Homozygotes exhibit lower fertility. Female homozygotes do not nurse well; up to 50% perinatal mortality can occur. No gene product (mRNA or protein) is detected by Northern or Western blot analysis of mouse embryonic fibroblasts. Homozygotes are only 80% of wildtype body weight at birth, and remain small. This mutant mouse strain may be useful in related to organismal growth.

Development
A targeting vector containing neomycin resistance and herpes simplex virus thymidine kinase genes was used to disrupt exons 4 through 7 and the 5' end of exon 8. The construct was electroporated into 129P2Ola/Hsd derived E14 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. The resulting chimeric male animals were crossed to C57BL/6 mice, and then backcrossed to the same for 10 generations (March 2003).

Molecular Note		A neomycin resistance gene was used to replace exons 4 through 7 and the 5' portion of exon 8. Exon 5 is known to encode an lysine residue essential for catalytic activity. Expression was undetected in homozygous mutant animals by both Northern and Western blot analyses. The authors noted that the expression of Akt2 and Akt3 was normal in mice homozygous for the targeted allele. [MGI Ref ID J:72176]

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.
