| FEN1 |
Flap endonuclease 1 |
DNA replication and repair |
Up |
Structure-specific nuclease involved in Okazaki-fragment maturation,
long-patch base-excision repair and replication-fork processing.
FEN1 is frequently overexpressed in cancer and can promote tumour-cell
proliferation, DNA-damage repair and treatment resistance. Therapeutic
inhibition or downregulation increases replication stress and DNA damage,
suppresses proliferation and may produce synthetic lethality in
homologous-recombination-deficient cancers.
