Target

  • Function

    E3 ubiquitin-protein ligase which binds polysumoylated chains covalently attached to proteins and mediates 'Lys-6'-, 'Lys-11'-, 'Lys-48'- and 'Lys-63'-linked polyubiquitination of those substrates and their subsequent targeting to the proteasome for degradation. Regulates the degradation of several proteins including PML and the transcriptional activator PEA3. Involved in chromosome alignment and spindle assembly, it regulates the kinetochore CENPH-CENPI-CENPK complex by targeting polysumoylated CENPI to proteasomal degradation. Regulates the cellular responses to hypoxia and heat shock through degradation of respectively EPAS1 and PARP1. Alternatively, it may also bind DNA/nucleosomes and have a more direct role in the regulation of transcription for instance enhancing basal transcription and steroid receptor-mediated transcriptional activation.
  • Tissue specificity

    Widely expressed at low levels in many tissues; highly expressed in testis.
  • Pathway

    Protein modification; protein ubiquitination.
  • Sequence similarities

    Contains 1 RING-type zinc finger.
  • Domain

    The RING-type zinc finger domain is required for the ubiquitination of polysumoylated substrates.
  • Post-translational
    modifications

    Sumoylated; conjugated by one or two SUMO1 moieties.
    Autoubiquitinated.
  • Cellular localization

    Cytoplasm. Nucleus. Nucleus > PML body. Nucleus > nucleoplasm.
