Recombinant Human FEN1, GST-tagged

• Cat.No.: FEN1-12841H
• Product Overview: Recombinant Human FEN1 protein, fused to GST-tag, was expressed in E.coli and purified by GSH-sepharose.

Specification

• Species: Human
• Source: E.coli
• Tag: GST
• Protein Length: 1-380a.a.
• Description: The protein encoded by this gene removes 5 overhanging flaps in DNA repair and processes the 5 ends of Okazaki fragments in lagging strand DNA synthesis. Direct physical interaction between this protein and AP endonuclease 1 during long-patch base excision repair provides coordinated loading of the proteins onto the substrate, thus passing the substrate from one enzyme to another. The protein is a member of the XPG/RAD2 endonuclease family and is one of ten proteins essential for cell-free DNA replication. DNA secondary structure can inhibit flap processing at certain trinucleotide repeats in a length-dependent manner by concealing the 5 end of the flap that is necessary for both binding and cleavage by the protein encoded by this gene. Therefore, secondary structure can deter the protective function of this protein, leading to site-specific trinucleotide expansions.
• Storage: The protein is stored in PBS buffer at -20℃. Avoid repeated freezing and thawing cycles.
• Storage Buffer: 1M PBS (58mM Na2HPO4,17mM NaH2PO4, 68mM NaCl, pH8. ) added with 100mM GSH and 1% Triton X-100,15%glycerol.
