||Recombinant human FEN-1 protein was expressed inE.coliand purified by using conventional chromatography techniques.
||FEN-1, also known as Flap structure-specific endonuclease 1, removes 5" overhanging flaps in DNA repair and processes the 5" ends of Okazaki fragments in lagging strand DNA synthesis. The protein is a member of the XPG/RAD2 endonuclease family and is one of ten proteins essential for cell-free DNA replication. FEN-1 is highly homologous to yeast Rad2. The C-terminal region of FEN-1 may bind to PCNA, thus allowing FEN-1 to function as an exonuclease in DNA replication.
