Target
-
FunctionApoptotic 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 specificityUbiquitous, except peripheral blood leukocytes.
-
Involvement in diseaseDefects 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 similaritiesBelongs to the IAP family.
Contains 3 BIR repeats.
Contains 1 RING-type zinc finger. -
DomainThe 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
modificationsUbiquitinated and degraded by the proteasome in apoptotic cells.
Phosphorylation by PKB/AKT protects XIAP against ubiquitination and protects the protein against proteasomal degradation. -
Cellular localizationCytoplasm.

Immunocytochemistry/ Immunofluorescence - Anti-XIAP antibody (ab2541)This image is courtesy of an Abreview submitted by Dr Kirk McManusab2541 (1/200) staining XIAP in HeLa cells (green). Cells were permeabilised with 0.5% Triton-X100/ PBS, fixed in methanol (-20oC, 10min) and counterstained with DAPI (red) in order to highlight the nucleus.

Immunocytochemistry/ Immunofluorescence - Anti-XIAP antibody (ab2541)ab2541 staining XIAP in MCF7 cells treated with forskolin (ab120058), by ICC/IF. Increase in XIAP expression correlates with increased concentration of forskolin, as described in literature.
The cells were incubated at 37°C for 2h in media containing different concentrations of ab120058 (forskolin) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab2541 (1 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody.
