Strain Information
Former Names B6.129S-Shhtm1(EGFP/cre)Cjt/J (Changed: 05-SEP-06 ) Type Congenic; Mutant Strain; Targeted Mutation; Additional information on Genetically Engineered Mutant Mice. Mating System +/+ sibling x Heterozygote (Female x Male) Species laboratory mouse Generation N6F2 (20-DEC-07) Donating Investigator Clifford Tabin, Harvard Medical School Description
This strain expresses a fusion product involving Enhanced Green Fluorescent Protein (EGFP) and Cre recombinase from the endogenous Shh locus. EGFP and cre expression are consistent with the endogenous gene. Fluorescence is detected in the distal posterior region of the limb buds of embryos aged embryonic day 10 to 12 and colocalizes with the endogenous gene product (mRNA). The donating investigator reports that it is not uncommon for a mosaic expression pattern to be exhibited when the allele is inherited through the female germline. It is recommended that this allele be passed through the male germline when conducting experiments involving cre-induced recombination. Mice homozygous for the mutation develop a limited limb skeleton and lack digit 2. 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.Development
A targeting vector containing a fusion product involving Enhanced Green Fluorescent Protein (EGFP) and Cre recombinase was inserted at the ATG of Shh and disrupted the sequence encoding the first 12 amino acids. 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 at least 5 generations.

Gene & Allele Information
| Allele Symbol | Shhtm1(EGFP/cre)Cjt | ||
|---|---|---|---|
| Allele Name | targeted mutation 1, Clifford J Tabin | ||
| Allele Type | Targeted (knock-in) | ||
| Common Name(s) | ShhCre/GFP; ShhGFP-Cre; Shhgfp-Cre; Shhgfpcre; | ||
| Mutation Made By | Clifford Tabin, Harvard Medical School | ||
| Site of Expression | Distal posterior region of the limb buds of embryos aged embryonic day 10 to 12; also a Cre strain. | ||
| Expressed Gene | GFP, Green Fluorescent Protein, jellyfish | ||
| Green Fluorescent Protein (GFP), derived from the jellyfish Aequorea victoria, is a versatile reporter molecule which has found use in many biological applications. In some constructs the original molecule has been modified in order to enhance its fluorescence intensity (EGFP, enhanced GFP). When utilized in a transgenic construct, tissue expressing sufficient amounts of GFP will fluoresce when exposed to a 488 nm light source. | |||
| 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. | |||
| Gene Symbol and Name | Shh, sonic hedgehog | ||

| Molecular Note | A cassette containing an in frame fusion between GFP and cre was inserted at the ATG. Upon recombination, the first 35 base pairs after the ATG were deleted. Fluorescence was detected in the distal posterior region of E10-E12 embryos. [MGI Ref ID J:92504] | ||

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
