Beta-1,3-N-acetylglucosaminyltransferase lunatic fringe (LFNG), human, recombinant

Organism: Homo sapiens (Human). Source: E.coli. Expression Region: 1-250aa. Protein Length: Full Length of Isoform 2. Tag Info: N-terminal GST-tagged. Target Protein Sequence: MTPGRCCLAA DIQVETFIFT DGEDEALARH TGNVVITNCS AAHSRQALSC KMAVEYDRFI ESGRKWFCHV DDDNYVNLRA LLRLLASYPH TRDVYVGKPS LDRPIQAMER VSENKVRPVH FWFATGGAGF CISRGLALKM SPWASGGHFM NTAERIRLPD DCTIGYIVEA LLGVPLIRSG LFHSHLENLQ QVPTSELHEQ VTLSYGMFEN KRNAVHVKGP FSVEADPSRF RSIHCHLYPD TPWCPRTAIF. Purity: Greater than 90% as determined by SDS-PAGE. Endotoxin: Not test. Biological Activity: n/a. Form: Liquid or Lyophilized powder. Buffer: 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, pH 8.0. Reconstitution: 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 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference. Storage: 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. Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4 °C for up to one week. Relevance: Glycosyltransferase that initiates the elongation of O-linked fucose residues attached to EGF-like repeats in the extracellular domain of Notch molecules. Decreases the binding of JAGGED1 to NOTCH2 but not that of DELTA1. Essential mediator of somite segmentation and patterning. Reference: "Clock regulatory elements control cyclic expression of Lunatic fringe during somitogenesis." Cole S.E., Levorse J.M., Tilghman S.M., Vogt T.F. Dev. Cell 3:75-84(2002). Function: Glycosyltransferase that initiates the elongation of O-linked fucose residues attached to EGF-like repeats in the extracellular domain of Notch molecules. Modulates NOTCH1 activity by modifying O-fucose residues at specific EGF-like domains resulting in inhibition of NOTCH1 activation by JAG1 and enhancement of NOTCH1 activation by DLL1 via an increase in its binding to DLL1 (By similarity). Decreases the binding of JAG1 to NOTCH2 but not that of DLL1
