|Antigen/Gene or Protein Targets||DR3 (Death Domain Receptor 3)|
|Relevance||In vivo study of DR3-induced apoptosis & function; in vivo sstudies of negative T cell selection and development. The DR3-/- mouse exhibits complete knockout of DR3, a death domain-containing tumour necrosis factor receptor. which mediates one of the key regulators of the cell division cycle. Negative selection and anti-CD3-induced apoptosis are significantly impaired in DR3-null mice. In contrast, both superantigen-induced negative selection and positive selection are normal. The pre-T-cell receptor-mediated checkpoint, which is dependent on TNFR signaling, is also unaffected in DR3-deficient mice. These data reveal a nonredundant in vivo role for this TNF receptor family member in the removal of self-reactive T cells in the thymus.|
|Production Details||A DR3 targeting vector, replacing the entire DR3 coding region with a loxP flanked resistance cassette, was transfected into GK129 ES cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. Chimeric offspring were bred with C57BL/6 mice to yield mice heterozygous for the mutant allele.|

|Method protocol||Primer information: DR3.2R - GAA AGG ATG AAA CTT GCC TGT TGG (same as R1); DR3.AV1 (neo) – CAT CGC CTT CTA TCG CCT TC; DR3.4F - AGA AGG AGA AAG TCA GTA GGA CCG (same as F1). Band sizes should be 280 bp for wildtype band, 320 bp for knockout band (NOTES: AV1 PRIMER NEEDS TO BE ULTRAPURE) Searches on the 2R and 4F primers flag espin but we were in between the espin and DR3 genes.|
Use 1.6% gel to view the bands.
