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, nicked Holliday junctions and
CC also intact Holliday junctions with a reduced efficiency. May be
CC required in mitosis for the processing of stalled or collapsed
CC replication fork intermediates. Plays a role in DNA repair and in
CC genotoxic stress-induced homologous recombination (HR) in somatic
CC cells. Mediates a subset of meiotic recombination events that are
CC insensitive to crossover interference (By similarity). {ECO:0000250}.
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250};
CC -!- SUBUNIT: Forms a heterodimer with EME1 (By similarity). Interacts with
CC RAD54. {ECO:0000250, ECO:0000269|PubMed:17327258}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1; Synonyms=Alpha;
CC IsoId=Q8GT06-1; Sequence=Displayed;
CC Name=2; Synonyms=Beta;
CC IsoId=Q8GT06-2; Sequence=VSP_044049, VSP_044050;
CC -!- TISSUE SPECIFICITY: Low expression in shoots and roots from etiolated
CC seedlings, and panicles after meiosis; moderate expression in young
CC panicles under differentiation of floral organs before and during
CC meiosis; and high expression in mature leaves.
CC {ECO:0000269|PubMed:17327258}.
CC -!- INDUCTION: By DNA-damaging treatments such as high intensity light, UV-
CC C and gamma-radiation. {ECO:0000269|PubMed:17327258}.
CC -!- SIMILARITY: Belongs to the XPF family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=EEE55999.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
