    N-terminal 10xHis-tagged
  • 产品提供形式：
    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.
  • 缓冲液：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

  • 功能：
    Bifunctional glycosyltransferase with both xylosyltransferase and beta-1,3-glucuronyltransferase activities involved in the biosynthesis of the phosphorylated O-mannosyl trisaccharide (N-acetylgalactosamine-beta-3-N-acetylglucosamine-beta-4-(phosphate-6-)mannose), a carbohydrate structure present in alpha-dystroglycan (DAG1). Phosphorylated O-mannosyl trisaccharid is required for binding laminin G-like domain-containing extracellular proteins with high affinity and plays a key role in skeletal muscle function and regeneration. LARGE elongates the glucuronyl-beta-1,4-xylose-beta disaccharide primer structure initiated by B4GAT1 by adding repeating units [-3-Xylose-alpha-1,3-GlcA-beta-1-] to produce a heteropolysaccharide.

    8. LARGE could act as a bifunctional glycosyltransferase, with xylosyltransferase and glucuronyltransferase activities, which produced repeating units of [-3-xylose-alpha1,3-glucuronic acid-beta1-]; allowed alpha-DG to bind laminin-G domain-containing ECM ligands PMID: 22223806

    11. LARGE has a role in inducing alpha-dystroglycan hyperglycosylation in skeletal and cardiac muscle PMID: 21203384
    12. This report extends our knowledge of the clinical phenotype associated with LARGE, and is the second family in which disease results from a large-scale gene rearrangement. PMID: 21248746
    13. LARGE2 was found to support the maturation of alpha-dystroglycan more effectively than LARGE. PMID: 15752776
    14. LARGE repression is responsible for the defects in dystroglycan-mediated cell adhesion that are observed in epithelium-derived cancer cells and point to a defect of dystroglycan glycosylation as a factor in cancer progression PMID: 19244252
