This gene encodes a protein that complexes with methyl methanesulfonate-sensitive UV-sensitive 81 protein to form an endonuclease complex. The encoded protein interacts with specifc DNA structures including nicked Holliday junctions, 3-flap structures and aberrant replication fork structures. This protein may be involved in repairing DNA damage and in maintaining genomic stability. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Oct 2009],cofactor:Magnesium.,function:Interacts with MUS81 to form a DNA structure-specific endonuclease with substrate preference for branched DNA structures with a 5-end at the branch nick. Typical substrates include 3-flap structures, replication forks and nicked Holliday junctions. May be required in mitosis for the processing of stalled or collapsed replication forks.,similarity:Belongs to the EME1/MMS4 family.,subcellular location:Recruited to regions of DNA damage in S-phase cells.,subunit:May self-associate. Interacts with MUS81. Interacts with ERCC4 and FANCM.,
