Comments
  • 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 and isoform 2 blocks etoposide-induced apoptosis.
  • SUBUNIT: Binds to caspase-9. Interaction with SMAC via the BIR domain disrupts binding to caspase-9 and apoptotic suppressor activity. Interacts with TAB1. In vitro, interacts with caspase-3 and caspase-7 via its BIR domain.
  • INTERACTION:

  • SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Nuclear, and in a filamentous pattern throughout the cytoplasm.
  • ALTERNATIVE PRODUCTS: 2 named isoforms [FASTA] produced by alternative splicing.

    SynonymsLivin alpha
    Isoform IDQ96CA5-1
    This is the isoform sequence displayed in this entry.
    Name1
    SynonymsLivin beta
    Isoform IDQ96CA5-2
    Features which should be applied to build the isoform sequence: VSP_002459.
  • TISSUE SPECIFICITY: 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 1 and isoform 2). Isoform 2 (but not isoform 1) is detected in fetal kidney, heart and spleen, and at lower levels in adult brain, skeletal muscle and peripheral blood leukocytes.
  • SIMILARITY: Belongs to the IAP family.
  • SIMILARITY: Contains 1 BIR repeat.
  • SIMILARITY: Contains 1 RING-type zinc finger.
