Strain Details

Type JAX® GEMM® Strain - Gene Trap Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Stock Type JAX® GEMM® Strain - Mutant Strain Mating System Heterozygote x +/+ sibling         (Female x Male) Species laboratory mouse Donating Investigator Philippe Soriano,   Fred Hutchinson Cancer Research Center Generation ?+F1 (27-APR-08)

Strain Description
Homozygotes occur at lower than Mendelian ratio (19%), and 20% die by age 1 week. Heterozygotes viable and fertile. No gene product is detected in homozygous embryos aged ED9.5-12.5 or in adult gonad. Homozygotes exhibit abnormalities in neural crest-derived and thoracic skeleton development, and palate bone fusion. These Schip1-mutant mice may be useful in studying cellular signaling in development and adult mice; specifically receptor tyrosine kinases (RTK; such as Ras, MAP kinase, PI3K and those in the platelet-derived growth factor (PDGF) family) and immediate early genes (IEG) induced shortly after RTK activation.

Strain Development
The retroviral gene-trap vector ROSAFARY (or reverse orientation splice acceptor for array) was designed with a promoter trap module (SAbgeo*pA; encoding a lacZ-neo fusion gene) and an frt-flanked poly-A trap module (PGKhygSD; PGK promoter-driven hygromycin gene with adenoviral splice donor). This construct was electroporated into 129S4/SvJaeSor-derived AK7.1 embryonic stem (ES) cells. ES cells with the ROSAFARY vector correctly targeted to the Schip1 gene (in the 2nd intron) were identified and used to generate mutant mice. Homozygous mice were maintained on a 129S4/SvJaeSor background prior to arrival at The Jackson Laboratory. The mice were then 002448 129S1/SvImJ (Stock No. 002448) for one generation.

The ROSAFARY vector inserts a promoterless lacZ-neo reporter fusion gene (which functions as an artificial 3' terminal exon to intercept and terminate transcription from the targeted gene promoter) as well as a poly-A trap (which functions as an artificial 5' terminal exon to initiate transcription from the insertion site). After inserting into an intron of an endogenous gene at a permissive site and in the correct orientation, the promoter trap module and the poly-A trap module can be activated to form fusion transcripts with the 5' or 3' exons.

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.
