UBC9 (UBE2I) Antibody (N-term)

Purified Rabbit Polyclonal Antibody (Pab)

  • WB - UBC9 (UBE2I) Antibody (N-term) AP1064a
    Western blot analysis of anti-UBE2I Antibody (N-term) (Cat.#AP1064a) in A2058 cell line lysates (35ug/lane). UBE2I(arrow) was detected using the purified Pab.
  • IHC-P - UBC9 (UBE2I) Antibody (N-term) AP1064a
    Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by AEC staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.
  • WB - UBC9 (UBE2I) Antibody (N-term) AP1064a
    Western blot analysis of UBE2I (arrow) using rabbit polyclonal UBE2I Antibody (S7) (Cat.#AP1064a). 293 cell lysates (2 ug/lane) either nontransfected (Lane 1) or transiently transfected (Lane 2) with the UBE2I gene.

Format Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is prepared by Saturated Ammonium Sulfate (SAS) precipitation followed by dialysis against PBS.
StorageMaintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.
PrecautionsUBC9 (UBE2I) Antibody (N-term) is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name UBE2I
Synonyms UBC9, UBCE9
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. 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'.
Cellular Location Nucleus. Cytoplasm. Note=Mainly nuclear. In spermatocytes, localizes in synaptonemal complexes. Recruited by BCL11A into the nuclear body (By similarity).
Tissue Location Expressed in heart, skeletal muscle, pancreas, kidney, liver, lung, placenta and brain. Also expressed in testis and thymus.

UBE2I (Ubc9) is a member of the E2 family and is specific for the conjugation of SUMO to a variety of target proteins. SUMO conjugation to target proteins is mediated by a different, but analogous, pathway to ubiquitinylation. This E2 is unusual in that it interacts directly with protein substrates that are modified by sumoylation, and may play a role in substrate recognition. UBE2I can mediate the conjugation of SUMO-1 to a variety of proteins including RanGAP1, I?B?, and PML without the requirement of an E3 ligase. UBE2I is essential for nuclear architecture and chromosome segregation.
