  • By making deletions of the promoter, we determined that only the proximal GAS box is required for LPS induction of Tap1 and Lmp2 [6].
  • These data suggest that NOD proteasome dysfunction is due to a tissue- and developmental-stage-specific defect in expression of the MHC-linked Lmp2 gene, resulting in altered transcription factor NF-kappaB activity, and that this defect contributes to pathogenesis in NOD mice [8].
  • Twenty-three breakpoints were confined within 5.4 kb in the Lmp-2 hotspot, and six breakpoints from the cas4 cross were located in the Pb hotspot, which we have now confined to a 15 kb segment [9].
  • Sequence analysis of the mouse gene encoding DELTA, designated Lmp19, indicates that it consists of six exons and five introns, similar to the Lmp2 gene [10].
