Summaries for FEN1 Gene

Entrez Gene Summary for FEN1 Gene

  • 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for FEN1 Gene

FEN1 (Flap Structure-Specific Endonuclease 1) is a Protein Coding gene. Diseases associated with FEN1 include Werner Syndrome and Xeroderma Pigmentosum, Group G. Among its related pathways are Chks in Checkpoint Regulation and Infectious disease. GO annotations related to this gene include magnesium ion binding and damaged DNA binding. An important paralog of this gene is GEN1.

UniProtKB/Swiss-Prot for FEN1 Gene

  • Structure-specific nuclease with 5-flap endonuclease and 5-3 exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5-end of a downstream Okazaki fragment. It enters the flap from the 5-end and then tracks to cleave the flap base, leaving a nick for ligation. Also involved in the long patch base excision repair (LP-BER) pathway, by cleaving within the apurinic/apyrimidinic (AP) site-terminated flap. Acts as a genome stabilization factor that prevents flaps from equilibrating into structurs that lead to duplications and deletions. Also possesses 5-3 exonuclease activity on nicked or gapped double-stranded DNA, and exhibits RNase H activity. Also involved in replication and repair of rDNA and in repairing mitochondrial DNA.

    • Interacts with PCNA. Three molecules of FEN1 bind to one PCNA trimer with each molecule binding to one PCNA monomer. PCNA stimulates the nuclease activity without altering cleavage specificity. The C-terminal domain binds EP300. Can bind simultaneously to both PCNA and EP300. Interacts with DDX11.

Post-translational modifications for FEN1 Gene

  • Acetylated by EP300. Acetylation inhibits both endonuclease and exonuclease activity. Acetylation also reduces DNA-binding activity but does not affect interaction with PCNA or EP300.
  • Methylation at Arg-192 by PRMT5 impedes Ser-187 phosphorylation and increases interaction with PCNA.
  • Phosphorylation upon DNA damage induces relocalization to the nuclear plasma. Phosphorylation at Ser-187 by CDK2 occurs during late S-phase and results in dissociation from PCNA.
  • Ubiquitination at Lys 8, Lys 171, and Lys 345
  • Modification sites at PhosphoSitePlus
