    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：
    Together with PI4K2A and the type III PI4Ks (PIK4CA and PIK4CB) it contributes to the overall PI4-kinase activity of the cell. This contribution may be especially significant in plasma membrane, endosomal and Golgi compartments. The phosphorylation of phosphatidylinositol (PI) to PI4P is the first committed step in the generation of phosphatidylinositol 4,5-bisphosphate (PIP2), a precursor of the second messenger inositol 1,4,5-trisphosphate (InsP3). Contributes to the production of InsP3 in stimulated cells and is likely to be involved in the regulation of vesicular trafficking.
  • 基因功能參考文獻：
    1. RNA interference of the type II phosphatidylinositol 4-kinases PI4KIIa and PI4KIIa in primary human endothelial cells leads to formation of an increased proportion of short WPB with perturbed packing of VWF, as exemplified by increased exposure of antibody-binding sites. PMID: 27068535
    2. Here two crystal structures are presented: the structure of human PIK42A and the structure of PIK42B containing a nucleoside analogue. PMID: 26143926
    3. Results provide evidence that type II PtdIns 4-kinase b was indeed recruited to CD4- p56lck complex upon CD4 receptor cross linking, suggests a mechanism for its association and a role for it in CD4-mediated intracellular calcium release. PMID: 24972704
    4. Canonical tyrosine residues mutation in FcepsilonRIgamma ITAM (Y65 and Y76) reveals that these two tyrosine residues in gamma subunit are required for its interaction with type II PtdIns 4-kinases. PMID: 24481753
    5. type II PtdIns 4-kinase beta is a key component in early T cell activation signaling cascades PMID: 23619705
    6. PIP4Kbeta interacts with and modulates nuclear localization of the PIP4Kalpha. PMID: 20583997
    7. There is no evidence to suggest that PI4K2B is contributing to bipolar disorder in this family but a role for this gene in schizophrenia has not been excluded. PMID: 19539307
    8. Type II PtdIns 4-kinase beta interacts with TCR-CD3 zeta chain. The C-terminal ITAM is critical for enzyme docking on the zeta chain. The association is tyrosyl phosphorylation dependent. Mutation of Y-151 & Y-142 disrupts interaction of the 2 proteins. PMID: 16337488
    9. UV irradiation increases nuclear PtdIns5P levels via inhibition of the activity of the beta isoform of PtdIns5P 4-kinase (PIP4Kbeta), an enzyme that can phosphorylate and remove PtdIns5P. PMID: 16949365
    10. LB-PI4K2B-1S-specific CD4(+) T cells contributed to the antitumor response by both directly eliminating malignant cells as effector cells and stimulating CD8(+) T cell immunity as helper cells. PMID: 18316730

  • 亞細胞定位：
    Cytoplasm. Membrane. Note=Mostly cytoplasmic but also found associated with the plasma membrane, the Golgi and endosomes. Compared to PI4K2A, a larger fraction of PI4K2B is cytosolic due to a smaller extent of palmitoylation. Translocates to membranes where it is recruited by PDGF stimulation by a Rac-GTP-dependent mechanism.
  • 蛋白家族：
    PI3/PI4-kinase family, Type II PI4K subfamily
  • 組織特異性：
    Widely expressed.
