Application Abreviews Notes
WB 1/2000 - 1/10000. Detects a band of approximately 53 kDa (predicted molecular weight: 53 kDa).
IP Use at 2-5 µg/mg of lysate.
IHC-P 1/1000 - 1/5000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • Function
    E3 ubiquitin ligase catalyzing the covalent attachment of ubiquitin moieties onto substrate proteins. These substrates include FILIP1, p53/TP53, CDKN1A and TERT. Keeps cells alive by suppressing p53/TP53 under normal conditions, but stimulates apoptosis by repressing CDKN1A under stress conditions. Acts as a negative regulator of telomerase. Has negative and positive effects on RNA polymerase II-dependent transcription.
  • Tissue specificity
  • Pathway
    Protein modification; protein ubiquitination.
  • Sequence similarities
    Contains 4 C3H1-type zinc fingers.
    Contains 1 RING-type zinc finger.
  • Post-translational
    Auto-ubiquitinated; which leads to proteasomal degradation.
