Strain Information

Traf2tm1Mak
Name: TNF receptor-associated factor 2; targeted mutation 1, Tak W Mak
Synonyms: TRAF2-
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 2
Alteration at locus: Knock-In
Traf2
Name: TNF receptor-associated factor 2
Type: Gene
Species: Mouse
Chromosome: 2
Alteration at locus: Knock-In
NCBI: 22030
Homologene: 22520
Genetic Alterations
The cDNA region encoding the Traf2 ring finger domain was mapped to two exons separated by a 1.7-kb intron. The targeting construct T-Traf2 was made by replacing the entire ring finger coding region and the intervening intron with the PGK-neo gene cassette in the reverse orientation to the endogenous Traf2 gene.
Genotype Determination
ES Cell Line
E14 derived from 129P2/OlaHsd
Phenotype
Traf2-/- mice appeared normal at birth but became progressively runted and died prematurely. Atrophy of the thymus and spleen and depletion of B cell precursors also were observed. Thymocytes and other hematopoietic progenitors were highly sensitive to TNF-induced cell death and serum TNF levels were elevated in these Traf2-deficient animals. Examination of Traf2-/- cells revealed a severe reduction in TNF-mediated JNK/SAPK activation but a mild effect on NF-kappaB activation. These results suggest that Traf2-independent pathways of NF-kappaB activation exist and that Traf2 is required for an NF-kappaB-independent signal that protects against TNF-induced apoptosis.

Strain Development
A genomic DNA clone for Traf2 was isolated by screening a 129/Sv/J mouse genomic DNA library using a probe derived from the 5′ end of the mouse Traf2 cDNA. The cDNA region encoding the Traf2 ring finger domain was mapped to two exons separated by a 1.7-kb intron. The targeting construct T-Traf2 was made by replacing the entire ring finger coding region and the intervening intron with the PGK-neo gene cassette in the reverse orientation to the endogenous Traf2 gene. Linearized T-Traf2 was then transfected into ES cells (E14) by electroporation. Neomycin-resistant ES clones were selected by 300 μg/ml G418 (Sigma) in Dulbecco's modified Eagle's medium supplemented with 15% fetal bovine serum and leukemia inhibitory factor. Homologous recombinants were identified by polymerase chain reaction (PCR) using a Traf2-specific primer downstream of the targeting construct (5′-ATA CAC TTG CAC AGA CAT ACA TGC AAG CAA-3′) and a primer in the PGK-neo gene cassette (5′-AAG CGC ATG CTC CAG ACT GCC TTG GGA A-3′). Genomic DNA was isolated from PCR-positive clones and analyzed by Southern blot hybridization using the flanking probe and a probe specific for the neomycin-resistance gene. The flanking probe was a radiolabeled 162 bp StuI–PstI fragment downstream of the targeting construct. ES clones confirmed for homologous recombination and a single PGK-neo insertion were injected into C57BL/6J blastocysts, which were then transferred into CD1 pseudopregnant foster mothers. The resulting male chimeras were backcrossed with C57BL/6J females, and germline transmission in F1 Traf2+/− mice was verified by Southern blot analysis. Traf2+/- mice were backcrossed 10 times into C57BL/6 mice from Jackson (JAX Strain #000664).
Suggested Control Mice
Traf2+/+ and Traf2+/- mice can be used as controls

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 csmmrrc@jax.org 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.

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.
