Genetic Alterations
ENU induced point mutation in the cording region.
This mutation was identified in a screen of progeny of ENU-treated mice for aberrant signal transduction through toll-like receptors (TLR). It substitutes G for A in the 9th of 11 exons, replacing a highly-conserved histidine with a positively-charged arginine at amino acid 412 (H412R), which resides in the ninth of 12 predicted transmembrane domains. Additional incidental mutations were detected in sequencing for the causative mutation, Unc93b13d, and may be present in stocks carrying this mutation.

Genotype Determination
ES Cell Line
NA
Phenotype
Homozygous: The 3d mutation causes a triple defect of macrophage response: a problem with sensing unmethylated DNA (CpG), dsRNA (poly I:C) and resiquimod. Hence signaling via TLRs 3, 7, and 9 is impaired. The mice are highly susceptible to infection with MCMV, presumably as a result of the multiple sensing defect. More moderate immunodeficiency is observed when mice are challenged with S. aureus, and diminished cytokine production is observed when macrophages from 3d homozygotes are infected with Listeria monocytogenes, particularly variant strains that cannot escape the endosome. In addition, 3d homozygotes show a defect of antigen processing/presentation via the class II pathway.

Strain Development

This mutation was identified in a screen of progeny of ENU-treated C57BL/6 mice for aberrant signal transduction through toll-like receptors (TLR). It substitutes G for A in the 9th of 11 exons, replacing a highly-conserved histidine with a positively-charged arginine at amino acid 412 (H412R), which resides in the ninth of 12 predicted transmembrane domains. Additional incidental mutations were detected in sequencing for the causative mutation, Unc93b13d, and may be present in stocks carrying this mutation. Mice are maintained n a C57BL/6J background.

Colony and Husbandry Information

Colony Surveillance Program and Current Health Reports

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email mmrrc@ucdavis.edu.

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to mmrrc@ucdavis.edu for more information.

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.

The donor or their institution limits the distribution to non-profit institutions only.

Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

010466-UCD-RESUS Litter recovered from cryo-archive $4,044.00 / Non-Profit Litter Recovered litter4; additional fees for any special requests.

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.
