CC -!- FUNCTION: Component of a DNA structure-specific endonuclease with
CC substrate preference for branched DNA structures with a 5'-end at the
CC branch nick. May be required in mitosis for the processing of stalled
CC or collapsed replication fork intermediates. May be required in meiosis
CC for the repair of meiosis-specific double strand breaks subsequent to
CC single-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}.
