Description
These Stk11 mutant mice possess loxP sites flanking exons 3-6 of the serine/threonine kinase 11 (Stk11) gene. Mice that are homozygous for this allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Stk11 is a member of the serine/threonine kinase family and regulates cell polarity and cell division, and controls cell energy expenditure. When bred to mice that express tissue-specific Cre recombinase, resulting offspring will have exons 3-6 deleted in the cre-expressing tissues. When bred to transgenic mice expressing Cre recombinase driven by myxovirus (influenza virus) resistance 1 (Mx1) promoter/enhanced elements, STK11 expression is abolished in hematopoietic cells. This strain may be useful for studying cell growth and tumor suppression.

For example, when crossed to a strain expressing tamoxifen-inducible Cre recombinase (see Stock No. 008085) or interferon-inducible Cre recombinase (see Stock No. 003556), this mutant mouse strain may be useful in studies of metabolic and cell cycle regulation.

Development
A targeting vector was designed to insert a loxP site followed by a Frt-flanked neomycin resistance cassette (neo) upstream of exon 3, and a second loxP site downstream of exon 6 of the serine/threonine kinase 11 (Stk11) gene. The construct was electroporated into Bruce4-derived C57BL/6 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts from B6(Cg)-Tyrc-2J/J mice (Stock No. 000058) and the resulting chimeric males were bred to female B6(Cg)-Tyrc-2J/J mice to establish a colony. These mice were then bred to mice carrying Tg(ACTFLPe)9205Dym to remove the neo cassette. Offspring were then backcrossed to C57BL/6 for at least 4 generations (See SNP note below). Upon arrival, mice were bred to C57BL/6J inbred mice (Stock No. 000664) for at least one generation to establish the colony.

A 32 SNP (single nucleotide polymorphism) panel analysis, with 27 markers covering all 19 chromosomes and the X chromosome, as well as 5 markers that distinguish between the C57BL/6J and C57BL/6N substrains, was performed on the rederived living colony at The Jackson Laboratory Repository. At least 11 the 32 markers on 5 chromosomes were found to be segregating. These data suggest the mice sent to The Jackson Laboratory Repository were on a mixed genetic background.

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.
