    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(biāo)簽：
    C-terminal 10xHis-tagged
  • 產(chǎn)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. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose.
  • 復(fù)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(chǔ)存條件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保質(zhì)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.
  • 注意事項(xiàng)：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
  • Datasheet & COA：
    Please contact us to get it.

靶點(diǎn)詳情

  • 功能：
    Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles. This isozyme has a high catalytic efficiency with 4-hydroxyalkenals such as 4-hydroxynonenal (4-HNE).
  • 基因功能參考文獻(xiàn)：
    1. These findings demonstrate GSTA4 activation during 4-HNE-induced neoplastic transformation in colorectal carcinogenesis. GSTA4 is a potential surrogate biomarker for CRC screening and should provide novel approaches for chemoprevention. PMID: 27065323
    2. Decreased gene expression of GSTA4 is associated with drug resistance in cervical cancer. PMID: 24403508
    3. drug resistance in three strains of tumor cells is associated with significant increase in hGSTP1 and hGSTA4 gene expression, whereas increased hGSTK1 gene expression was detected only in resistant erythroleukemia and mammary adenocarcinoma cells. PMID: 23330092
    4. GSTA4 down-regulation and the concomitant increase in 4-hydroxynonenal adducts in muscle are indicative of susceptibility to infection in individuals with severe thermal injuries. PMID: 22038048
    5. Data show that mandatory overexpression of hGSTA4 by transient transfection in KYSE30 cells and attenuation of HNE-induced EGFR phosphorylation. PMID: 21751261
    6. analysis of four novel mutations that change the function of leukotriene C(4) synthase and are associated with increased risk of venous thromboembolism and ischemic stroke PMID: 20456754
    7. Gsta4/GSTA4 is a novel susceptibility gene for NMSC that affects risk in both mice and humans. PMID: 20966433
    8. Results indicate that downregulation of GSTA4 in adipose tissue leads to increased protein carbonylation, ROS production, and mitochondrial dysfunction and may contribute to the development of insulin resistance and type 2 diabetes. PMID: 20150287
    9. GSTA4-4 exploits the hydroxyl group of either 4R- or 4S-hydroxynonenal (HNE), while specifically binding HNE and glutathione (GSH) to maintain high catalytic efficiency linked with stereoselective product formation for both enantiomeric substrates. PMID: 20085333
    10. null mice had a significantly lower survival time than wild-type controls when chronically treated with relatively low doses of paraquat, a finding consistent with a role of glutathione transferase A4-4 in the defense against oxidative stress PMID: 14761685
    11. We now demonstrate that hGSTA4-transfection also causes a profound change in the expression of genes involved in cell adhesion, cell cycle control, proliferation, cell growth, and apoptosis. PMID: 16005854
    12. we observed a single nucleotide polymorphism (SNP) G351A leading to the silent mutation Gln117Gln.No significant difference was observed in the distribution of this GSTA4 polymorphism between Parkinson disease individuals and healthy controls PMID: 16054170
    13. The effect of over-expression of GSTA4 mRNA on the sensitivity of HepG2 cells to 4-hydroxynonenal injury is reported. PMID: 17553661
    14. These results demonstrate that oxidative stress mediated disruption of tight junctions in endothelial cells may be attenuated by hGSTA4-4 expression. PMID: 18080870
    15. GSTA4-4 may play an important defensive role against atherogenesis through detoxification of 4-HNE and upregulation of inducible nitric oxide synthase PMID: 18485437
    16. genetic polymorphisms in GSTA4 had modification effects on smoking-related lung cancer risk, particularly among patients with squamous cell carcinoma and small-cell-lung-cancer. PMID: 18767114
    17. 4-HNE is involved in p53-mediated signaling in in vitro cell cultures as well as in vivo that can be regulated by glutathione transferase PMID: 18930016
