  • Function

    Protects against apoptosis induced by TNF or by chemical agents such as adriamycin, etoposide or staurosporine. Suppression of apoptosis is mediated by activation of MAPK8/JNK1, and possibly also of MAPK9/JNK2. This activation depends on TAB1 and NR2C2/TAK1. In vitro, inhibits caspase-3 and proteolytic activation of pro-caspase-9. Isoform 1 blocks staurosporine-induced apoptosis. Isoform 2 blocks etoposide-induced apoptosis.
  • Tissue specificity

    Isoform 1 and isoform 2 are expressed at very low levels or not detectable in most adult tissues. Detected in adult heart, placenta, lung, lymph node, spleen and ovary, and in several carcinoma cell lines. Isoform 2 is detected in fetal kidney, heart and spleen, and at lower levels in adult brain, skeletal muscle and peripheral blood leukocytes.
  • Sequence similarities

    Belongs to the IAP family.
    Contains 1 BIR repeat.
    Contains 1 RING-type zinc finger.
  • Cellular localization

  • ab127979 at 1/100 staining Livin in 4% paraformaldehyde fixed, 0.1% Triton X-100 permeabilized HeLa cells by Immunocytochemistry.
  • 2 µg of ab127979 was added to aliquots of cleared cell lysates from transfected HeLa cells and incubated for 2 hr at 4°C. Protein-G Dynabeads were then added, and lysates were incubated for additional 2 hr at 4°C to capture the IgG-protein complex. Anti-V5 antibody was used in parallel as a positive control. As a negative control, primary antibody was excluded.
