Strain Information

Irf7m1Btlr
Name: interferon regulatory factor 7; mutation 1, Bruce Beutler
Synonyms: inept
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 7
Alteration at locus: Chemically Induced
Irf7
Name: interferon regulatory factor 7
Type: Gene
Species: Mouse
Chromosome: 7
Alteration at locus: Chemically Induced
NCBI: 54123
HGNC: HGNC:6122
Homologene: 128624
Genetic Alterations
A missense mutation occurred at nucleotide 749 of the Irf7 transcript (located in exon 4 of 10; Genbank record NM_016850), causing an aspartic acid to glycine substitution at residue 110 of the IRF7 protein.
Genotype Determination
Phenotype

Homozygotes: Homozygotes lack in vivo Type I IFN production in response to TLR9 (CpG injection) and TLR7 (resiquimod) signaling. Macrophages display normal TNF-alpha production in response to all TLR signaling and are resistant to viral infection.
Heterozygotes: Heterozygotes lack in vivo Type I IFN production in response to TLR7 signaling (resiquimod).

Mammalian Phenotype Terms

  • immune system
Strain Development
The inept mutation was generated on a C57BL/6J background by ENU mutagenesis. The strain has been maintained on this background.
Suggested Control Mice

Wild-type littermates or C57BL/6J mice

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 mmrrc@ucdavis.edu. Older strains may not have this information.

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.

Units Notes
032796-UCD-RESUS Litter recovered from cryo-archive $4,044.00 / Non-Profit Litter Recovered litter4; additional fees for any special requests.
Cryopreserved material may be available upon request, please inquire to mmrrc@ucdavis.edu for more information.

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.
