Exons 3 and 4 of the mouse Nov gene are flanked by loxP sites. Brain-specific cre-mediated excision of the floxed region in the brain results in a mild anxiolytic effect.

Exons 3 and 4 of mouse Nov (nephroblastoma overexpressed gene) is flanked by loxP sites. Cre-mediated excision of the floxed region results in a knockout allele.
Crosses with CamKIIA-Cre mice result in a knockout of Nov expression in brain, and a mild anxiolytic (anxiety-inhibiting) effect is observed. There is no obvious effect on the circadian clock.
BAC clone RP24-289J3, containing the mouse Nov gene was used to introduce an FRT-flanked neomycin resistance gene followed by a loxP site in intron 2, and another loxP site in intron 4. The mutation was created through homologous recombination in B6(Cg)-Tyrc-2J/J-derived LR2-6-1 embryonic stem (ES) cells. Resultant chimeric mice were crossed to B6;SJL-Tg(ACTFLPe)9205Dym/J animals (see Stock No. 003800) to excise the neomycin cassette. This strain has been backcrossed to C57BL/6J for 6 generations by the donating lab.

Molecular Note | BAC clone RP24-289J3, containing the mouse Nov gene, was used to introduce an FRT-flanked neomycin resistance gene followed by a loxP site in intron 2, and another loxP site in intron 4. Flp-mediated recombination removed the FRT-flanked neo cassette. |
Homozygous and heterozygous floxed mice are viable and fertile.

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. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
