Strain Information

Name: TNF receptor-associated factor 6; targeted mutation 1, Tak Mak
Synonyms: TRAF6-
Type: Allele
Species: Multi-species
Chromosome: 2
Alteration at locus: Knock-In
Name: TNF receptor-associated factor 6
Synonyms: 2310003F17Rik, C630032O20Rik
Type: Gene
Species: Mus musculus (mouse)
Chromosome: 2
Alteration at locus: Knock-In

Genetic Alterations
The targeting vector was engineered to replace the exon containing the ATG translation initiation codon with PGK-neo in the opposite orientation. This exon encodes the first 100 amino acids of Traf6, representing a portion of the amino-terminal ring-finger domain.
Genotype Determination
ES Cell Line
E14K derived from 129P2/OlaHsd
Mice deficient in TNF receptor-associated factor 6 (Traf6) are osteopetrotic with defects in bone remodeling and tooth eruption due to impaired osteoclast function. In vitro assays, Traf6 is crucial not only in IL-1 and CD40 signaling but also, surprisingly, in LPS signaling. Furthermore, like Traf2 and Traf3, Traf6 is essential for perinatal and postnatal survival. Thus Traf6 plays diverse and critical roles in perinatal and postnatal survival, bone metabolism, LPS, and cytokine signaling

Strain Development
The murine Traf6 gene was disrupted by introducing a targeted mutation into embryonic stem cells (E14K) by homologous recombination (see also: Genetic Alterations). Two independent heterozygous (TRAF6+/−) mutant ES cell lines were microinjected into C57BL/6 (B6) blastocysts, which were subsequently implanted into pseudopregnant CD-1 (ICR) recipients. Male chimeras generated from both cell lines were used to generate TRAF6+/− mice. TRAF6 +/- mice were backcrossed 10 times into C57BL/6 mice from Jackson (JAX Strain #000664).
Suggested Control Mice
Traf6+/+ AND Traf6+/- can be used as controls.
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.

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 for more information.

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

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.

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.

Cryopreserved material may be available upon request, please inquire to for more information.

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.
