    text
  • SUMO-2/3 localize to centromeres and condensed chromosomes
  • ARHGAP21 co-localizes with SUMO2/3 in the cytoplasm and membrane compartments
  • basic FUNCTION
  • involved in the function and/or structure of the eukaryotic kinetochore
  • ubiquitin-like protein that can be conjugated to other proteins in a manner analogous to ubiquitination
  • SUMO-2/3 conjugation and the ubiquitin-proteasome system are tightly integrated and act in a cooperative manner
  • with other SUMO proteins, binding to lysine residues of target proteins and thereby modifying their stability, activity and subcellular localization
  • with SUMO2 and SUMO1 accumulate at DNA double-strand breaks sites in mammalian cells, with SUMO1 and SUMO2/3 accrual requiring the E3 ligase enzymes PIAS4 and PIAS1
  • SUMO2 and SUMO3 can rapidly convert to be conjugated in response to a variety of cellular stresses
  • CELLULAR PROCESS protein, degradation
    PHYSIOLOGICAL PROCESS cellular trafficking transport
    PATHWAY

    a component
  • kinetochore
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • targeting proteins
  • covalently binding and modifying RANGAP1 involved in nuclear transport
  • interacting with CENPE (CENPE was found to be modified specifically by SUMO-2/3 and to possess SUMO-2/3 polymeric chain-binding activity essential for kinetochore localization)
  • cell & other
    REGULATION
    repressed by expression of SUMO3, can be down-regulated at the transcription level by cellular oxidative stress
