    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：
    N-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：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
  • 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(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.

靶點詳情

  • 功能：
    Choline-specific phosphodiesterase that hydrolyzes sphingomyelin releasing the ceramide and phosphocholine and therefore is involved in sphingomyelin digestion, ceramide formation, and fatty acid (FA) absorption in the gastrointestinal tract. Has also phospholipase C activity and can also cleave phosphocholine from palmitoyl lyso-phosphatidylcholine and platelet-activating factor (PAF) leading to its inactivation. Does not have nucleotide pyrophosphatase activity. May promote cholesterol absorption by affecting the levels of sphingomyelin derived from either diet or endogenous sources, in the intestinal lumen.

    7. alk-SMase activity is severely affected by defective N-glycosylation at 5 sites and by structural alterations of the putative metal-binding sites and the predicted active core. PMID: 15458386
    8. Results describe the cloning of rat alkaline sphingomyelinase from rat intestine, comparison to the human sequence, adjustment of the putative protein in GenBank, and confirmation of the specific expression of the gene in the small intestine. PMID: 15708357
    9. Alkaline sphingomyelinase hydrolyses and inactivates PAF by a phospholipase C activity, a novel function by which it may counteract the development of intestinal inflammation and colon cancer. PMID: 16255717
