  • Function

    Mediates E3-dependent ubiquitination and proteasomal degradation of target proteins, including p53/TP53, HDAC1 and CDKN1B. Preferentially acts on tetrameric p53/TP53. Contributes to the regulation of CDKN1B and p53/TP53 levels, and thereby contributes to the regulation of the cell cycle progression. Increases AR transcription factor activity.
  • Pathway

    Protein modification; protein ubiquitination.
  • Sequence similarities

    Contains 1 CHY-type zinc finger.
    Contains 1 CTCHY-type zinc finger.
    Contains 1 RING-type zinc finger.
  • Post-translational

    Subject to ubiquitination and proteasomal degradation. Interaction with PLAGL2 or KAT5 enhances protein stability.
  • Cellular localization

    Nucleus. Nucleus speckle. Cytoplasm.
