CC   -!- FUNCTION: Catalytic subunit of the SLX1-SLX4 structure-specific
CC       endonuclease that resolves DNA secondary structures generated during
CC       DNA repair and recombination. Has endonuclease activity towards
CC       branched DNA substrates, introducing single-strand cuts in duplex DNA
CC       close to junctions with ss-DNA. {ECO:0000255|HAMAP-Rule:MF_03100}.
CC   -!- COFACTOR:
CC       Name=a divalent metal cation; Xref=ChEBI:CHEBI:60240;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_03100};
CC   -!- SUBUNIT: Forms a heterodimer with SLX4. {ECO:0000255|HAMAP-
CC       Rule:MF_03100}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|HAMAP-Rule:MF_03100}.
CC   -!- SIMILARITY: Belongs to the SLX1 family. {ECO:0000255|HAMAP-
CC       Rule:MF_03100}.
