    Avi-tag Biotinylated

    E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

  • 蛋白標簽：
    Tag?type?will?be?determined?during?the?manufacturing?process.
    The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
  • 產品提供形式：
    Lyophilized powder
    Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
  • 復溶：
    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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
  • 儲存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質期：
    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.
  • 貨期：
    Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
    Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet ：

靶點詳情

  • 功能：
    Catalyzes the 2 serial methylation steps for the conversion of the 7-monomethylguanosine (m(7)G) caps of snRNAs and snoRNAs to a 2,2,7-trimethylguanosine (m(2,2,7)G) cap structure. The enzyme is specific for guanine, and N7 methylation must precede N2 methylation. Hypermethylation of the m7G cap of U snRNAs leads to their concentration in nuclear foci, their colocalization with coilin and the formation of canonical Cajal bodies (CBs). Plays a role in transcriptional regulation.

    1. Data highlight the importance of the catalytic activity of PIMT to mediate VEGF effects during endothelial cell migration and tube formation in angiogenesis. PMID: 26738492
    2. Self-association of Tgs1p and its catalytic activity were prerequisite to bypass the requirement for its accessory factor Swm2p for efficient pre-rRNA processing and snRNA trimethylation. PMID: 26074133
    3. PIMT was identified as a key player responsible for glycated low density lipoproteins induced vascular endothelial cell apoptosis. PMID: 23922881
    4. isoforms of the PIMT/Tgs1 protein with an RNA methyltransferase domain function both in the nucleus and in the cytoplasm PMID: 12943661
    5. The protein L-isoaspartyl (D-aspartyl) methyltransferase (PIMT) is an enzyme that recognizes and repairs the abnormal L-isoaspartyl residues in proteins. PMID: 21204776
    6. The structure-function data highlight a strictly essential pi-cation interaction between Trp766 and the m(7)G base and a network of important enzymic contacts to the cap triphosphate via Lys646, Tyr771, Arg807, and Lys836. PMID: 20360394
    7. Interaction of PIMT with transcriptional coactivators CBP, p300, and PBP differential role in transcriptional regulation. PMID: 11912212
    8. proteasome maturation constitutes a mechanism regulating Tgs1 function by generating Tgs1 species with different substrate specificities, subcellular localizations, and functions. PMID: 18039666
    9. These results highlight that PIMT expression is regulated by ROS and could primarily act as an antioxidant enzyme. PMID: 18407833
    10. present a biochemical characterization of the human Tgs1 guanine-N2 methyltransferase reaction and identify individual amino acids required for methyltransferase activity in vitro and in vivo PMID: 18775984
    11. m(7)GpppA binds via its adenosine moiety to the structurally conserved adenosylmethionine-binding pocket. The m(7) guanosine is unbound. The crystallized TGS1 fragment is catalytically inactive, but a fragment that is 17 AAs longer exhibits activity. PMID: 19307714
    12. The crystal structure of the substrate bound methyltransferase domain as well as mutagenesis studies provide insight into the catalytic mechanism of TGS1. PMID: 19386620
