  • 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.

    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：
    3-7 business days
  • 注意事項(xiàng)：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

靶點(diǎn)詳情

  • 功能：
    Transfers the sialyl group (N-acetyl-alpha-neuraminyl or NeuAc) from CMP-NeuAc to the non-reducing terminal galactose (Gal) of glycosphingolipids forming gangliosides (important molecules involved in the regulation of multiple cellular processes, including cell proliferation and differentiation, apoptosis, embryogenesis, development, and oncogenesis). Mainly involved in the biosynthesis of ganglioside GM3 but can also use different glycolipids as substrate acceptors such as D-galactosylceramide (GalCer), asialo-GM2 (GA2) and asialo-GM1 (GA1), although less preferentially than beta-D-Gal-(1->4)-beta-D-Glc-(1<->1)-Cer (LacCer).

    1. While no differences in clinical characteristics were detected in patients possessing the functional promoter haplotypes of ST3GAL5, exophthalmic values were significantly lower in patients with the ST8SIA1 haplotype, which showed a significant increase in promoter activity PMID: 29047240
    2. These cases broaden the phenotypic and genetic spectrum of GM3 synthase deficiency due to ST3GAL5 variants. Patients with intellectual disability or furthermore presenting with Rett-like phenotype should be suspected of GM3 synthase deficiency, a disorder of ganglioside biosynthesis. PMID: 27232954
    3. Data suggest that ganglioside glycosyltransferases ST3GAL5, ST8SIA1, and B4GALNT1 are S-acylated at conserved cysteine residues located close to cytoplasmic border of their transmembrane domains; ST3Gal-II is acylated at conserved cysteine residue in N-terminal cytoplasmic tail; for B4GALNT1 and ST3Gal-II, dimer formation controls their S-acylation status. PMID: 28698248
    4. Studied the miRNA expression in human hepatocellular carcinoma cell lines; 13 differentially expressed miRNAs were identified between MHCC97-H and MHCC97-L cells; and the same results were found in clinical samples. Found that ST3GAL5 was the direct target of miR-26a, miR-548l and miR-34a. PMID: 28218742
    5. Serum deprivation triggers upregulation of hST3Gal V gene expression through Runx2 activation by BMP signaling in MG-63 cells. PMID: 26729095
    6. Whole-exome sequencing of patients with salt and pepper syndrome shows a homozygous c.994G>A transition (p.E332K) in the ST3GAL5 gene. PMID: 24026681
    7. GM3 synthase deficiency, responsible for early-onset epilepsy syndrome, leads to a secondary respiratory chain dysfunction. PMID: 22990144
    8. Data demonstrate that valproic acid (VPA) transcriptionally regulates human GM3 synthase (hST3Gal V), which catalyzes ganglioside GM3 biosynthesis in ARPE-19 human retinal pigment epithelial cells. PMID: 21699754
    9. GM3 exhibits the potential to regulate the allosteric structural transition from inactive to a signaling EGFR dimer, by preventing the autophosphorylation of the intracellular kinase domain in response to ligand binding PMID: 21571640
    10. In vivo expression of the transcript gives rise to two human ST3Gal-V isoforms with distinct characteristics. PMID: 20219466
    11. ST6Gal I and ST3Gal V were positively correlated with the high risk of pediatric acute leukemia. PMID: 19709745
    12. GM3 synthase overexpression results in reduced cell motility and in caveolin-1 upregulation in human ovarian carcinoma cells PMID: 19759399
    13. GM3 synthase mRNA levels were significantly higher in differentiated human monocyte-derived macrophages compared to monocytes and in atherosclerotic aorta compared to normal aorta PMID: 19415461
    14. isolation and characterization of the promoter region PMID: 12393190
    15. enhanced expression of GM3 synthase through protein kinase C /extracellular regulated kinases-dependent cAMP-responsive element binding protein activation by phorbol 12-myristate 13-acetate is associated with the differentiation of HL-60 cells PMID: 15385432
    16. ). We sequenced genes in the region and identified a nonsense mutation in SIAT9, which is predicted to result in the premature termination of the GM3 synthase enzyme (also called lactosylceramide alpha-2,3 sialyltransferase). PMID: 15502825
    17. These results are the first demonstration of the existence of a new isoform of human GM3 synthase, which could play an important role during HL60 cell differentiation. PMID: 16934889
    18. GM3 synthase point mutation almost completely depletes human fibroblast cellular gangliosides, dampens membrane EGFR activation, and modulates related critical cell functions such as proliferation and migration PMID: 18480157
    19. Ganglioside GM3 inhibits VEGF/VEGFR-2-mediated angiogenesis. Direct interaction of GM3 with VEGFR-2 is reported. PMID: 18974200
