- 说明书：
Description: Flap endonuclease-1 (FEN-1) is a structure-specific nuclease with multiple functions in DNA processing pathways (1, 2). The replication and DNA repair activities of FEN-1 are critical for genomic stability in the eukaryotic cell. Through interaction with proliferation cell nuclear antigen (PCNA), FEN-1 helps coordinate Okazaki fragment maturation by removing RNA-DNA primers (3). FEN-1 is also required for non-homologous end joining of double stranded DNA breaks in long patch base excision repair (4, 5). The multi-functional activities of FEN-1 are regulated by various mechanisms, including protein partner interactions (6, 7), post-translational modifications (8, 9), and subcellular re-localization in response to cell cycle or DNA damage (10).
Function: 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.
Subunit Structure: Three molecules of FEN1 bind to one PCNA trimer with each molecule binding to one PCNA monomer (PubMed:15616578). PCNA stimulates the nuclease activity without altering cleavage specificity (PubMed:15616578). The C-terminal domain binds EP300; can bind simultaneously to both PCNA and EP300 (PubMed:11430825). Interacts with PCNA; can bind simultaneously to both PCNA and EP300 (PubMed:9305916, PubMed:11430825). Interacts with DDX11; this interaction is direct and increases flap endonuclease activity of FEN1 (PubMed:18499658).
Post-translational Modifications: 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. 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. Methylation at Arg-192 by PRMT5 impedes Ser-187 phosphorylation and increases interaction with PCNA.
Similarity: Belongs to the XPG/RAD2 endonuclease family. FEN1 subfamily.
