CC -!- FUNCTION: Structure-specific nuclease with 5'-flap endonuclease and 5'-
CC 3' exonuclease activities involved in DNA replication and repair.
CC During DNA replication, cleaves the 5'-overhanging flap structure that
CC is generated by displacement synthesis when DNA polymerase encounters
CC the 5'-end of a downstream Okazaki fragment. It enters the flap from
CC the 5'-end and then tracks to cleave the flap base, leaving a nick for
CC ligation. Also involved in the long patch base excision repair (LP-BER)
CC pathway, by cleaving within the apurinic/apyrimidinic (AP) site-
CC terminated flap. Acts as a genome stabilization factor that prevents
CC flaps from equilibrating into structures that lead to duplications and
CC deletions. Also possesses 5'-3' exonuclease activity on nicked or
CC gapped double-stranded DNA, and exhibits RNase H activity. Also
CC involved in replication and repair of rDNA and in repairing
CC mitochondrial DNA. {ECO:0000256|HAMAP-Rule:MF_03140}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_03140};
CC Note=Binds 2 magnesium ions per subunit. They probably participate in
CC the reaction catalyzed by the enzyme. May bind an additional third
CC magnesium ion after substrate binding. {ECO:0000256|HAMAP-
CC Rule:MF_03140};
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleolus {ECO:0000256|HAMAP-
CC Rule:MF_03140}. Nucleus, nucleoplasm {ECO:0000256|HAMAP-Rule:MF_03140}.
CC Mitochondrion {ECO:0000256|HAMAP-Rule:MF_03140}. Note=Resides mostly in
CC the nucleoli and relocalizes to the nucleoplasm upon DNA damage.
CC {ECO:0000256|HAMAP-Rule:MF_03140}.
CC -!- SIMILARITY: Belongs to the XPG/RAD2 endonuclease family. FEN1
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_03140}.
