    Product Description

    Flap endonuclease 1 (FEN1), a RAD2 Class II nuclease, plays a crucial role in DNA repair, replication, and genomic stability.1 FEN1 removes the 5'-unannealed flap during Okazaki fragment processing in lagging strand DNA synthesis.2 Removal of the DNA flap is also critical in long-patch base excision repair and regulation of recombination.3 In yeast, FEN1 mutants display sensitivity to UV irradiation, deficient chromosome segregation, and cell cycle arrest in S phase.4 Furthermore, haploinsufficiency of FEN1 in mice leads to rapid tumor progression.4 FEN1 is overexpressed in many forms of cancer, including lung, gastric, prostate, pancreatic, brain, and breast.3
