  • Application notes
    Is unsuitable for Flow Cyt,ICC/IF,IHC-P or IP.
  • Target

    • Function

      Apoptotic suppressor. Has E3 ubiquitin-protein ligase activity. Mediates the proteasomal degradation of target proteins, such as caspase-3, SMAC or AIFM1. Inhibitor of caspase-3, -7 and -9. Mediates activation of MAP3K7/TAK1, leading to the activation of NF-kappa-B.
    • Tissue specificity

      Ubiquitous, except peripheral blood leukocytes.
    • Involvement in disease

      Defects in XIAP are the cause of lymphoproliferative syndrome X-linked type 2 (XLP2) [MIM:300635]. XLP is a rare immunodeficiency characterized by extreme susceptibility to infection with Epstein-Barr virus (EBV). Symptoms include severe or fatal mononucleosis, acquired hypogammaglobulinemia, pancytopenia and malignant lymphoma.
    • Sequence similarities

      Belongs to the IAP family.
      Contains 3 BIR repeats.
      Contains 1 RING-type zinc finger.
    • Domain

      The first BIR domain is involved in interaction with TAB1/MAP3K7IP1 and is important for dimerization. The second BIR domain is sufficient to inhibit caspase-3 and caspase-7, while the third BIR is involved in caspase-9 inhibition. The interactions with SMAC and PRSS25 are mediated by the second and third BIR domains.
    • Post-translational

      Ubiquitinated and degraded by the proteasome in apoptotic cells.
      Phosphorylation by PKB/AKT protects XIAP against ubiquitination and protects the protein against proteasomal degradation.
