E3 SUMO-protein ligase RanBP2 (RANBP2), partial, human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 2601-2802aa. Protein Length: Partial. Tag Info: N-terminal 6xHis-B2M-tagged. Target Protein Sequence: PTEESSINYT FKTPEKAKEK KKPEDSPSDD DVLIVYELTP TAEQKALATK LKLPPTFFCY KNRPDYVSEE EEDDEDFETA VKKLNGKLYL DGSEKCRPLE ENTADNEKEC IIVWEKKPTV EEKAKADTLK LPPTFFCGVC SDTDEDNGNG EDFQSELQKV QEAQKSQTEE ITSTTDSVYT GGTEVMVPSF CKSEEPDSIT KS. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0. Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: E3 SUMO-protein ligase which facilitates SUMO1 and SUMO2 conjugation by UBE2I. Involved in transport factor (Ran-GTP, karyopherin)-mediated protein import via the F-G repeat-containing domain which acts as a docking site for substrates. Binds single-stranded RNA (in vitro). May bind DNA. Component of the nuclear export pathway. Specific docking site for the nuclear export factor exportin-1. Sumoylates PML at 'Lys-490' which is essential for the proper assembly of PML-NB. Recruits BICD2 to the nuclear envelope and cytoplasmic stacks of nuclear pore complex known as annulate lamellae during G2 phase of cell cycle.
