  • 复溶：
    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.
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保质期：
    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.
  • 货期：
    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.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

  • 功能：
    Involved in intracellular vesicle trafficking and vesicle fusion with membranes. Contributes to the granule exocytosis machinery through interaction with soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) proteins that regulate membrane fusion. Regulates cytotoxic granule exocytosis in natural killer (NK) cells.
  • 基因功能参考文献：
    1. Neonatal platelets exhibit low levels of the Stx11-Munc18b complex (essential component of the SNARE machinery) and of beta1-tubulin. These developmental deficiencies are associated with defects in platelet adhesion, spreading and secretion. PMID: 29044293
    2. Among these nine polymorphisms, rs188212047 [G/T (L212F)] of STXBP2 was significantly (dominant model; P = 4.84 x 10-8; odds ratio, 2.94) associated with myocardial infarction. STXBP2 may thus be a novel susceptibility locus for myocardial infarction in Japanese. PMID: 28380445
    3. STXBP2 Gene Polymorphism is associated with Hemophagocytic Lymphohistocytosis. PMID: 27513731
    4. Mutation in STXBP2 gene is associated with hemophagocytic lymphohistiocytosis. PMID: 27781387
    5. Data show that Munc18b overexpression increased fusion of not only newcomer secretory granule (SG), but also predocked SGs in type-2 diabetes (T2D) human and Goto-Kakizaki Rat Islets. PMID: 28163042
    6. two novel mutations of STXBP2: c.184A>G and c.577A>C. c.184A>G (p.Asn62Asp) was located within a highly conserved region of the STXBP2 protein and predicted to be deleterious. PMID: 26451869
    7. mutations result in severe chronic active Epstein-Barr virus disease PMID: 25947952
    8. red blood cells express Munc18-2 and that erythroid cells from patients with FHL-5 exhibit intrinsic defects caused by STXBP2/Munc18-2 mutations. PMID: 26320718
    9. Munc18-2(R65Q) and Munc18-2(R65W) retain the ability to interact with and stabilize STX11. However, presence of Munc18-2(R65Q/W) in patient-derived lymphocytes and forced expression in control CTLs and NK cells diminishes degranulation and cytotoxicity. PMID: 25564401
    10. Data show that all but one patient with atypical familial hemophagocytic lymphohistiocytosis carried at least one splice-site mutation in UNC13D or STXBP2. PMID: 20823128
    11. Munc18-2 binds the N-terminal peptide of Stx11 with a ~20-fold higher affinity than Stx3, suggesting a potential role in selective binding. PMID: 24194549
    12. We report that FHL-5 neutrophils have a profound defect in granule mobilization, resulting in inadequate bacterial killing, in particular, of gram-negative Escherichia coli, but not of Staphylococcus aureus. PMID: 23687090
    13. Mutations in STXBP2 do not only affect cytotoxic T lymphocytes but also cause changes in the intestinal and renal epithelium resulting in severe, osmotic diarrhea and renal proximal tubular dysfunction PMID: 23382066
    14. Novel mutation in STXBP2 prevents IL-2-induced natural killer cell cytotoxicity in familial hemophagocytic lymphohistiocytosis. PMID: 22336081
    15. We report the largest cohort of patients with FHL5 so far, describe an extended disease spectrum, and demonstrate for the first time a clear genotype-phenotype correlation. PMID: 22451424
    16. Missense and splice-site sequence variants in PRF1, MUNC13-4, and STXBP2 were found in 25 (14%) of the adult patients. The A91V-PRF1 genotype was found in 12 of these patients (48%). PMID: 21881043
    17. Data show that 3 novel mutations of STXBP2 gene were confirmed. PMID: 21152410
    18. Biallelic STXBP2 mutations were identified in families with familial haemophagocytic lymphohistiocytosis. PMID: 20798128
    19. mutation analysis, clinical presentation, and functional analysis of NK cells in patients with mutations in STXBP2 encoding Munc18-2, recently associated with familial hemophagocytic lymphohistiocytosis type 5 PMID: 20558610
    20. STXBP2 is required at a late step of the secretory pathway for the release of cytotoxic granules by binding syntaxin 11, another component of the intracellular membrane fusion machinery. PMID: 19884660
    21. binds to syntaxins 1A, 2, and 3 and regulates vesicle transport to the apical plasma membrane PMID: 12198139
    22. Munc18-2 acts as a regulator of primary granule exocytosis, while Munc18-3 may preferentially regulate the fusion of secondary granules PMID: 18588921
    23. Familial hemophagocytic lymphohistiocytosis type 5 (FHL-5) is caused by mutations in Munc18-2 and impaired binding to syntaxin 11 PMID: 19804848
