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.
貨期:
Basically, we can dispatch the products out in 1-3 working days
after receiving your orders. 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.
注意事項(xiàng):
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
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.

results reveal that the LARGE-glycan of dystroglycan serves as a tunable extracellular matrix protein scaffold, the extension of which is required for normal skeletal muscle function PMID: 24132234
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
This study demonistreated that Intragenic rearrangements in LARGE gene in muscle-eye-brain disease. PMID: 21727005
the ligand-binding activity of alpha-dystroglycan is conferred primarily by LARGE modification at Thr-317 and -319, within the highly conserved first 18 amino acids of the mucin-like domain PMID: 21987822
LARGE has a role in inducing alpha-dystroglycan hyperglycosylation in skeletal and cardiac muscle PMID: 21203384
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
LARGE2 was found to support the maturation of alpha-dystroglycan more effectively than LARGE. PMID: 15752776
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
