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|ARBA:ARBA00029382}.
