Protein name:
Flap endonuclease 1 (FEN-1) ;
Alternative:
Flap structure-specific endonuclease 1 ;DNase IV ;Maturation factor 1 (MF1;hFEN-1) ;
Organism:
Human (Homo sapiens).
General Annotation
Sub Unit:
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.
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.
Subcellular Location:

Resides mostly in the nucleoli and relocalizes to the nucleoplasm upon DNA damage.
