Generation DefinitionsDonating Investigator Marc Ekker, University of Ottawa Description
Homozygous Dlx5/6-Cre transgenic mice are viable and fertile. Expression of Cre recombinase (Cre) is directed to differentiating and migrating forebrain GABAergic neurons during embryonic development by the I56i and I56ii enhancers from the zebrafish dlx5a/dlx6a intergenic region (with the 5' promoter region of zebrafish dlx6a in place to increase the activity of the intergenic enhancers rather than direct tissue-specific expression). When Dlx5/6-Cre transgenic mice are bred with mice containing a loxP-flanked sequence, Cre-mediated recombination will result in deletion of the floxed sequence in the offspring in the offspring. These Dlx5/6-Cre transgenic mice may be useful in generating specific deletions of floxed alleles in GABAergic forebrain neurons.Development
The Dlx5/6-Cre transgene was designed with a 3.5 kb fragment from the immediate 5'-flanking region of zebrafish dlx6a gene (including part of the 5' UTR) placed immediately upstream of a Cre recombinase coding sequence, all followed by a 1.4 kb enhancer fragment from the zebrafish dlx5a/dlx6a intergenic region (containing both zebrafish I56i and I56ii enhancers). The donating investigator reports that a female founder mouse (founder #8561 on a CD1 genetic background) was bred to CD1 males and the resulting Dlx5/6-Cre mice were maintained by breeding hemizygous males with CD1 females for at least 10 generations prior to arrival at The Jackson Laboratory Repository. Upon arrival, transgenic animals were bred with C57BL/6J mice for at least one generation to establish the colony.

Gene & Allele Information provided by MGI
| Allele Symbol | Tg(dlx6a-cre)1Mekk | ||
|---|---|---|---|
| Allele Name | transgene insertion 1, Marc Ekker | ||
| Allele Type | Transgenic (Cre/Flp) | ||
| Common Name(s) | Dlx5/6-Cre; Dlx5/6i-Cre; Tg(dlx6a-cre)1Mars; | ||
| Mutation Made By | Marc Ekker, University of Ottawa | ||
| Site of Expression | GABAergic forebrain neurons | ||
| 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 | dlx6a, distal-less homeobox gene 6a, Danio rerio, | ||
| Driver Note | dlx6a | ||
| Molecular Note | A cre gene was placed under the control of the I56i and I56ii enhancer elements of zebrafish dlx5a and a 3.5kb genomic DNA fragment flanking the 5' region of the zebrafish dlx6a open reading frame and containing the 5'UTR. The dlx6a flanking region on its own cannot produce tissue specific expression but increases the activity of the enhancers to produce expression that recapitulate endogenous Dlx5 expression. Tissue specific expression was confirmed by test crosses to reporter mice strains, including Tg(ACTB-Bgeo/ALPP)1Lbe, Tg(ACTB-Bgeo/GFP)21Lbe and Gt(ROSA)26Sortm1Sor. [MGI Ref ID J:122066] | ||

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 Information
