  • 产品描述：

    CUSABIO synthesized the recombinant gene by integrating the N-terminal GST tag sequence into the targeted gene encoding the 1-157aa of the human UBE2I. The synthesized gene was subsequently cloned into an expression vector. After cloning, the expression vector was introduced into the E.coli for expression. The product was purified to obtain the recombinant human UBE2I protein carrying N-terminal GST tag. The SDS-PAGE assayed the purity of this recombinant UBE2I protein greater than 90%. This UBE2I protein migrated along the gel to a band of about 45 kDa molecular weight.

    UBE2I is a gene providing instruction of making a protein named SUMO-conjugating enzyme UBC9 (also called Ubiquitin-protein ligase I and abbreviated as p18) in human and belongs to Ubiquitin-conjugating enzyme family. SUMO is an abbreviated form of small ubiquitin-like modifiers. SUMOylation is a process of covalent and reversible attaching of SUMO moiety to a target protein and is an important post-translational modification involved in various cellular processes. UBC9 is the unique SUMO E2 enzyme known ro conjugate SUMO to target substrates. The UBC9 serves as a lynchpin in the SUMO conjugateion pathway, interecting with the SUMO E1 during activation.

  • 功能：
    Accepts the ubiquitin-like proteins SUMO1, SUMO2, SUMO3, SUMO4 and SUMO1P1/SUMO5 from the UBLE1A-UBLE1B E1 complex and catalyzes their covalent attachment to other proteins with the help of an E3 ligase such as RANBP2, CBX4 and ZNF451. 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'. Mediates sumoylation of ERCC6 which is essential for its transcription-coupled nucleotide excision repair activity.

PMID: 29956745
    2. Data show that the forkhead Box Protein P3 (FOXP3) response element at the -310 bp region, but not the -2182 bp region, is mainly required for ubiquitin conjugating enzyme 9 (UBC9) activation by FOXP3. PMID: 30011797
