CC -!- FUNCTION: Interacts with EME1 to form a DNA structure-specific
CC endonuclease with substrate preference for branched DNA structures with
CC a 5'-end at the branch nick. Typical substrates include 3'-flap
CC structures, D-loops, replication forks and nicked Holliday junctions.
CC May be required in mitosis for the processing of stalled or collapsed
CC replication fork intermediates. May be required in meiosis for the
CC repair of meiosis-specific double strand breaks subsequent to single-
CC end invasion (SEI) (By similarity). {ECO:0000250}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC -!- SUBUNIT: Interacts with EME1. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the XPF family. {ECO:0000305}.
