== Function ==
[https://www.uniprot.org/uniprot/HJC_SACS2 HJC_SACS2] A structure-specific endonuclease that resolves Holliday junction (HJ) intermediates during genetic recombination; may have some degree of sequence preference in a mobile junction. Cleaves 4-way DNA junctions introducing paired nicks in opposing strands, leaving a 5'-terminal phosphate and a 3'-terminal hydroxyl group that are ligated to produce recombinant products. Can cleave all 4 strands 3 bases 3' of the junction center. Cleaves both mobile and immobile junctions. Modifies the structure of the 4-way DNA junction, a model Holliday junction structure. The protein forms multiple complexes with 4-way DNA, suggesting more than 1 homodimer can bind to each junction.<ref>PMID:10701121</ref> <ref>PMID:10736227</ref> <ref>PMID:10940317</ref> <ref>PMID:11709558</ref> <ref>PMID:17011573</ref>
