Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Targeted Mutation Mating System +/+ sibling x Heterozygote (Female x Male) Species laboratory mouse Donating Investigator Clifford Tabin, Harvard Medical School Generation N5+1F2 (08-JAN-08) Strain Description
This strain expresses a fusion product involving Cre recombinase and a mutant form of the human estrogen receptor ligand binding domain from the endogenous Shh locus. The mutant human estrogen receptor does not bind natural ligand at physiological concentrations but will bind the synthetic ligand, 4-hydroxytamoxifen. Restricted to the cytoplasm, the Cre/ESR1 protein can only gain access to the nuclear compartment after exposure to tamoxifen. Tamoxifen administration induces Cre recombinase expression in all cells that express the endogenous gene resulting in the deletion of the first 35 base pairs following the ATG. Homozygous mice are not viable or fertile. Heterozygous mutant mice are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This mutant mouse strain may be useful in studies of limb patterning and development.Strain Development
A targeting vector containing a fusion product involving Cre recombinase and a mutant form of the human estrogen receptor ligand binding domain was inserted at the ATG of Shh. The construct was electroporated into 129S6/SvEv-derived TC-1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric animals were crossed to C57BL/6 mice, and then backcrossed to the same for 5 generations.

| Site of Expression | tamoxifen inducible Cre recombinase protein fused to a mutant form of the human estrogen receptor ligand binding domain; expression in all cells that express the Shh gene | ||
| 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. | |||

| Molecular Note | A cassette containing CreERT2 was inserted at the ATG. Upon recombination, the first 35 base pairs after the ATG were deleted. Cre was produced in all cells in which the endogenous mRNA was normally expressed. [J:92504] | ||

| 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. |
