    Note: The complete sequence may include tag sequence, target protein sequence, linker sequence and extra sequence that is translated with the protein sequence for the purpose(s) of secretion, stability, solubility, etc.
    If the exact amino acid sequence of this recombinant protein is critical to your application, please explicitly request the full and complete sequence of this protein before ordering.
  • 蛋白標簽：
    N-terminal GST-tagged
  • 產品提供形式：
    Liquid or 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.
  • 緩沖液：
    If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
    Note: If you have any special requirement for the glycerol content, please remark when you place the order.
    If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
  • 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：
    3-7 business days
  • 注意事項：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

靶點詳情

  • 功能：
    Catalyzes the phosphorylation of the ketose sugar fructose to fructose-1-phosphate.
  • 基因功能參考文獻：
    1. Data indicate metabolic enzymes NAD kinase and ketohexokinase as candidate metabolic gene targets, and the chromatin remodeling protein INO80C as a tumor suppressor in KRAS(MUT) colorectal tumor xenograft. PMID: 28954733
    2. Angelica archangelica, Garcinia mangostana, Petroselinum crispum, and Scutellaria baicalensis were the top four botanical candidiates identified with inhibitory activity against ketohexokinase-C. PMID: 27322374
    3. compared with normal hepatocytes, hepatocellular carcinoma (HCC) cells markedly reduce the rate of fructose metabolism and the level of reactive oxygen species, as a result of a c-Myc-dependent and heterogeneous nuclear ribonucleoprotein (hnRNP) H1- and H2-mediated switch from expression of the high-activity fructokinase (KHK)-C to the low-activity KHK-A isoform. PMID: 27088854
    4. myocardial hypoxia actuates fructose metabolism in human and mouse models of pathological cardiac hypertrophy through hypoxia-inducible factor 1alpha (HIF1alpha) activation of SF3B1 and SF3B1-mediated splice switching of KHK-A to KHK-C PMID: 26083752
    5. These studies identify fructokinase as a novel mediator of diabetic nephropathy and document a novel role for endogenous fructose production, or fructoneogenesis, in driving renal disease. PMID: 24876114
    6. This study determined if single nucleotide polymorphisms in genes involved in fructose transport,SLC2A2 and SLC2A5 and metabolism, etohexokinase affect inter-individual variability in metabolic phenotypes. PMID: 23341889
    7. In human hepatocytes uric acid up-regulates KHK expression thus leading to the amplification of the lipogenic effects of fructose. PMID: 23112875
    8. ketohexokinase-A serves an unknown physiologic function that remains intact in essential fructosuria. PMID: 12941785
    9. The expression of ketohexokinase is diminished in human clear cell type of renal cell carcinoma PMID: 16372272
    10. Ketohexokinase-dependent metabolism of fructose induces proinflammatory mediators in proximal tubular cells. PMID: 19158351
    11. The structure of the KHK-A ternary complex revealed an active site with fructose & the ATP analogue in positions ready for phosphorylation. The effects of the pathogenic mutations Gly40Arg & Ala43Thr have been modelled in the context of the KHK structure. PMID: 19237742
