Strain Information
Former Names B6.FVB(CD1)-Tg(Neurog3-cre)C1Able/J (Changed: 09-MAY-07 ) Type Congenic; Mutant Strain; Transgenic; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Additional information on Congenic nomenclature. Mating System +/+ sibling x Hemizygote (Female x Male) 08-JUN-08 Species laboratory mouse Generation N5F5 (28-JAN-09) Donating Investigator IMR Colony, The Jackson Laboratory Description
Mice hemizygous for the transgenic insert are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. Expression of the transgene is directed by a neurogenin 3 promoter. Tissues where Cre recombinase expression is detected include the small intestine (base of intestinal crypts) and fetal pancreatic epithelial cells. Cre activity has been shown in islets of the adult pancreas, small intestine enteroendocrine cells, endocrine portions of the stomach, all pancreatic endocrine cells, and in some non-endocrine intestinal cells. When bred with a mouse containing a loxP site-flanked sequence of interest, Cre-mediated recombination results in deletion of the flanked gene in the tissues that normally express neurogenin 3.In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.
Development
A bacterial artificial chromosome (BAC) encoding the mouse neurogenin 3 sequence was modified by the insertion of a cre recombinase gene, preceded by nuclear localization sequence, into exon 1 of the neurogenin 3 gene at the initiator methionine. The BAC was injected into FVB/N embryos which were next implanted into pseudopregnant CD1 females. Founder line C1 was obtained and backcrossed to CD1 mice for 7 generations after which mice were intercrossed. The mice were then backcrossed to C57BL/6J for 5 generations.

Gene & Allele Information
| Allele Symbol | Tg(Neurog3-cre)C1Able | ||
|---|---|---|---|
| Allele Name | transgene insertion C1, Andrew B Leiter | ||
| Allele Type | Transgenic (Cre/Flp) | ||
| Common Name(s) | Neurog3(cre); Tg(Neurog3-cre)#Able; ngn3-Cre; | ||
| Mutation Made By | Andrew Leiter, Univ. of Massachusetts Medical School | ||
| Site of Expression | small intestine (base of intestinal crypts) and fetal pancreatic epithelial cells | ||
| 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 | Tg(Neurog3-cre)C1Able, transgene insertion C1, Andrew B Leiter | ||
| Chromosome | UN | ||
| Gene Common Name(s) | Neurog3(cre); Tg(Neurog3-cre)#Able; ngn3-Cre; transgene insertion #, Andrew B Leiter; | ||
| Driver Note | Neurog3 | ||
| General Note | This is one of two independent lines demonstrating identical expression patterns. | ||
| Molecular Note | The Cre recombinase coding sequence, flanked by a nuclear localization signal and an SV40 polyadenylation site, was inserted just after the translation start site of the neurogenin 3 gene present in mouse BAC RP23-121F10, which also includes approximately 81 kb of 5' and 102 kb of 3' flanking DNA. Immunohistochemical analysis shows the same expression pattern for cre as for neurogenin 3 in adult and embryonic mice bearing this transgene. Cre recombinase activity is seen in cell types of pancreas, stomach, small intestine and colon that express or are descended from cells that express neurogenin 3 during development.

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
