Genetic Alterations

ES Cell Line
D3
Phenotype
Homozygous: Mice that are homozygous for the targeted mutation are viable, fertile, and normal in size. No gene product (mRNA) is detected by Northern blot analysis of homozygous primary embryonic fibroblasts. Mice that are homozygous for this targeted allele lack type I IFN receptor function, exhibit enhanced osteoclastogenesis with decreased bone density, and impaired response to protozoan parasite (Leishmania) infection. NK cell mediated tumor regression does not occur in homozygotes in response to B16 melanoma tumor implant model. Mouse mutants involving this gene have been used in studies of Zika virus pathogenesis.

Heterozygous: Not characterized

Strain Development
A targeting vector containing neomycin resistance and herpes simplex virus thymidine kinase genes was used to disrupt exon 3. The construct was electroporated into 129S2/SvPas derived D3 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The mice were backcrossed to C57BL/6 for at least 5 generations, as reported by the donating investigator.

MMRRC Genetic QC Summary
The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact csmmrrc@jax.org. Older strains may not have this information.

    Colony and Husbandry Information

    When maintaining a live colony, these mice can be bred as homozygotes. SPF conditions are recommended.

    For more information about this colony's health status contact csmmrrc@jax.org

    Order Request Information

    Colony is sized to accommodate orders of approximately 10 mice within the age range of 4-8 weeks. Larger quantities may be available, please contact the distributing center directly for more details at csmmrrc@jax.org.

    Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

    1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

    2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

    3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

    4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
