When crossed with a Cre recombinase-expressing strain, this floxed mutant strain is useful in eliminating tissue-specific expression of the Erc1 (ELKS/RAB6-interacting/CAST family member 1) gene.

Targeted (Conditional ready (e.g. floxed), No functional change) | Erc1 | ELKS/RAB6-interacting/CAST family member 1 |
A 5'UTR exon and the first coding exon of the Erc1 (ELKS/RAB6-interacting/CAST family member 1; ELKS1, CAST2) gene are flanked by loxP sites in these floxed mutant mice. Mice that are homozygous for this floxed allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Normal expression of the targeted gene is demonstrated by the floxed allele.
A targeting vector was designed to flank a 5'UTR exon, the first coding exon, and an FRT-flanked neomycin cassette with loxP sites. The vector was introduced to (129X1/SvJ x 129S1/Sv)F1- Kitl+-derived R1 embryonic stem (ES) cells. The neomycin selection cassette was excised from chimeric animals though crosses with an Actb beta actin promoter Flp recombinase mouse originally made on a B6SJLF2 background, and possibly backcrossed to C57BL/6NCrl. This strain was maintained on a predominantly C57BL/6 and 129 mixed background by the donating laboratory.

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.
