Type JAX® GEMM® Strain - Mutant Stock Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Transgenic Mating System Hemizygote x +/+ sibling (Female x Male) Species laboratory mouse Donating Investigator George Cotsarelis, University of Pennsylvania Generation N?+N1F8 (27-APR-08) Strain Description
Mice hemizygous for the transgenic insert are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These transgenic mice have a synthetic steroid RU 486 inducible Cre-mediated recombination system driven by the mouse keratin complex 1, acidic, gene 15 promoter. The transgene insert contains a fusion product involving Cre recombinase and a mutant form of the human progesterone receptor. The mutant human progesterone receptor does not bind natural ligand at physiological concentrations but will bind the synthetic ligand, RU 486. Restricted to the cytoplasm, the Cre/PGR protein can only gain access to the nuclear compartment after exposure to RU 486. When crossed with a strain containing a loxP site flanked sequence of interest, the offspring are useful for generating RU 486-induced, Cre-mediated targeted deletions. This strain represents an effective tool for generating tissue-specific targeted mutants that would be useful to study epithelial and hair follicle stem cells lineage.Strain Development
A transgenic construct containing sequence encoding cre/PGR under the control of the mouse keratin complex 1, acidic, gene 15 promoter, was introduced into B6SJLF1 donor eggs.

|---|---|---|---|
| Allele Name | transgene insertion 22, George Cotsarelis | ||
| Common Name(s) | K15-CrePR1; | ||
| Mutation Made By | Yaping Liu, University of Pennsylvania | ||
| Strain of Origin | (C57BL/6J x SJL/J)F2 | ||
| Site of Expression | when crossed with a strain containing a loxP site flanked sequence of interest, the offspring are useful for generating RU 486-induced, cre-mediated targeted deletions | ||
| Expressed Gene | PGR, progesterone receptor, human | ||
| Expressed Gene | cre, cre recombinase, bacteriophage P1 | ||
| Cre recombinase is an enzyme derived from the bacteriophage P1 that specifically recognizes loxP sites. Cre has been shown to effectively mediate the excision of DNA located between loxP sites. After the excision event, the DNA ends recombine leaving a single loxP site in place of the intervening sequence. | |||
| Promoter | Krt15, keratin 15, mouse, laboratory | ||
| General Note | This transgenic line is one of seven founder lines expressing the transgene, as assessed by RT-PCR. Mice of each line were crossed to mice expressing a beta-galactosidase Cre reporter transgene. Following topical application of RU486, bitransgenic mice of lines 22, 42 and 49 were shown to exhibit beta-galactosidase activity in their skin. Line 22, which showed the least enzyme activity in untreated skin, was selected for further analysis. | ||
| Molecular Note | The transgene comprises the entire 5.0-kb mouse Krt1-15 promoter region driving expression of a fusion protein composed of an amino-terminal nuclear localization signal followed by Cre recombinase joined to the carboxyl-terminal hormone binding domain (HBD) of a mutant human progesterone receptor. This mutant HBD, whose carboxyl terminal is truncated by 42 amino acids, fails to bind endogenous progestins but binds and, paradoxically, is activated by progesterone receptor antagonists such as RU486. Constitutive expression of the fusion protein is directed by the Krt1-15 promoter to epithelial stem cells in the bulge region of the hair follicle. It remains inactive in the cytoplasm until bound to RU486, whereupon it translocates to the nucleus and can catalyze loxP-mediated recombination.

Supply Details
| Standard Supply | Repository-Live. A collection of over 1000 strains maintained as live colonies. Individual colonies are sized to meet current customer demand. Delivery for orders of 10 mice or less ranges on average from one to eight weeks; mice are generally shipped between four to six weeks of age with a maximum shipping age of ~nine weeks. Colony sizes do not generally support stringent age specifications for large volumes of mice; however custom orders and larger quantities of mice are easily arranged. Estimated ship dates for all orders provided within 48 hours of order placement. |

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 and Purchasing Information
