Biological background
Protein function (datasheet): 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. Can catalyze the formation of poly- SUMO chains. Necessary for sumoylation of FOXL2 and KAT5. Essential for nuclear architecture and chromosome segregation. Sumoylates p53/TP53 at 'Lys-386'. .
Scientific background (datasheet): SUMO-conjugating enzyme UBC9 (UBE2I), also called UBC9, is a protein that in humans is encoded by the UBE2I gene. This gene encodes a member of the E2 ubiquitin-conjugating enzyme family. It is mapped to 16p13.3. UBC9 could fully complement the mutant phenotype of a yeast ubc9 mutant strain. This gene may play a similar role via interaction with WT1, which is able to impose a block to cell cycle progression in eukaryotic cells. What's more, it could support the growth of yeast ubc9 temperature-sensitive mutants at nonpermissive temperatures, indicating that the gene is a functional homolog of yeast ubc9. UBC9 is specifically associated with FHIT, such as FHIT may be involved in cell cycle control through its interaction with UBC9.
Cellular localization (datasheet): Nucleus. Cytoplasm. Mainly nuclear. In spermatocytes, localizes in synaptonemal complexes. Recruited by BCL11A into the nuclear body (By similarity). .
Tissue details (datasheet): Expressed in heart, skeletal muscle, pancreas, kidney, liver, lung, placenta and brain. Also expressed in testis and thymus. .
Sequence similarities (datasheet): Belongs to the ubiquitin-conjugating enzyme family.
Research relevance and current trends
- Commonly studied in contexts related to Cell Biology,2339,Epigenetics and Nuclear Signaling,Metabolism,Obesity,Proteasome / Ubiquitin,Proteolysis/Ubiquitin,Ubiquitin & Ubiquitin Like Modifiers.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- ELISA: Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.
- Immunohistochemistry (IHC): Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.
- Flow cytometry: Quantify target-positive populations in single-cell suspensions; pair with viability and isotype/FMO controls conceptually.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.
