Generation DefinitionsDonating Investigator Jeremy Nathans, Johns Hopkins University Description
These targeted mutation mice carry a tamoxifen-inducible Cre cassette knocked into the 3' UTR of the gene. When crossed with a strain containing a loxP site flanked sequence of interest, the offspring are useful for generating 4-hydroxytamoxifen-induced, Cre-mediated targeted deletions specifically in cholinergic neurons. Heterozygotes and homozygotes are normal in size, viability and fertility.Development
An IRES-creER cassette followed by an Frt-PGK-Neo-Frt selectable marker was knocked in to the 3' UTR of the gene using a 129-derived JHMI-ES1 embryonic stem cell line. The PGK-Neo was removed by crossing to a C57BL/6 background Flp recombinase strain. Flp was then bred out of the line. This strain was maintained on a mixed C57BL/6 and 129 background by the donating laboratory.

Gene & Allele Information provided by MGI
| Allele Symbol | Chattm1(cre/ERT)Nat | ||
|---|---|---|---|
| Allele Name | targeted mutation 1, Jeremy Nathans | ||
| Allele Type | Targeted (knock-in) | ||
| Common Name(s) | ChAT-IRES-creER(T); Chattm1(cre/Esr1)Nat; | ||
| Strain of Origin | 129 | ||
| ES Cell Line Name | Other (see notes) | ||
| ES Cell Line Strain | 129 | ||
| Site of Expression | cholinergic neurons (after induction) | ||
| 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. | |||
| Driver Note | Chat | ||
| General Note | ES cell line = JHMI-ES1. | ||
| Inducible Note | Induced by tamoxifen. | ||
| Molecular Note | An IRES-creER cassette, a tetracycline resistance gene, and a Frt-flanked neomycin selection marker were all knocked in to the 3' UTR of the gene. The neomycin selection marker was removed by crossing to a C57BL/6 background Flp recombinase strain. Flp was then bred out of the line. When crossed with a Tg(CAG-Bgeo/ALPP)1Lbe reporter strain and given tamoxifen, cre expression was detected in amacrine cells of the retina, and in a sparse number of cholinergic neurons in the brain.

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
