  • Function
    Accepts the ubiquitin-like proteins SUMO1, SUMO2, SUMO3 and SUMO4 from the UBLE1A-UBLE1B E1 complex and catalyzes their covalent attachment to other proteins with the help of an E3 ligase such as RANBP2 or CBX4. Necessary for sumoylation of FOXL2 and KAT5. Essential for nuclear architecture and chromosome segregation.
  • Tissue specificity
    Expressed in heart, skeletal muscle, pancreas, kidney, liver, lung, placenta and brain. Also expressed in testis and thymus.
  • Pathway
    Protein modification; protein sumoylation.
  • Sequence similarities
    Belongs to the ubiquitin-conjugating enzyme family.
  • Cellular localization
    Nucleus. Cytoplasm. Mainly nuclear. In spermatocytes, localizes in synaptonemal complexes. Recruited by BCL11A into the nuclear body.

  • ab75854, at 1/100 dilution, staining UBE2I / UBC9 in human brain, by Immunohistochemistry using formalin-fixed, paraffin-embedded tissue.
  • UBE2I / UBC9 was immunoprecipitated using 0.5mg Jurkat whole cell extract, 5µg of Rabbit polyclonal to UBE2I / UBC9 and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).
    The antibody was incubated under agitation with Protein G beads for 10min, Jurkat whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.
    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70oC; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab75854.
    Secondary: Clean blot (HRP conjugate) at 1/1000 dilution.
    Band: 18kDa: UBE2I / UBC9; non specific - 60kDa: We are unsure as to the identity of this extra band.
  • ab75854 staining UBE2I / UBC9 (red) in cerebral cortex of Ubc9 transgenic mice, by Immunohistochemistry (Frozen sections). Left panel shows all layers of cerebral cortex, and right panel shows an enlarged region of the Layer III-External pyramidal area.

    Samples were incubated with primary antibody at 1 µg/ml and an AlexaFluor®700-conjugated goat anti-rabbit IgG (1 µg/ml) was used as the secondary antibody.
  • Overlay histogram showing HepG2 cells stained with ab75854 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab75854, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
