Non-catalytic subunit of the structure-specific, heterodimeric DNA endonuclease MUS81-EME2 which is involved in the maintenance of genome stability. In the complex, EME2 is required for DNA cleavage, participating in DNA recognition and bending. MUS81-EME2 cleaves 3'-flaps and nicked Holliday junctions, and exhibit limited endonuclease activity with 5' flaps and nicked double-stranded DNAs. MUS81-EME2 which is active during the replication of DNA is more specifically involved in replication fork processing. Replication forks frequently encounter obstacles to their passage, including DNA base lesions, DNA interstrand cross-links, difficult-to-replicate sequences, transcription bubbles, or tightly bound proteins. One mechanism for the restart of a stalled replication fork involves nucleolytic cleavage mediated by the MUS81-EME2 endonuclease. By acting upon the stalled fork, MUS81-EME2 generates a DNA double-strand break (DSB) that can be repaired by homologous recombination, leading to the restoration of an active fork. MUS81-EME2 could also function in telomere maintenance.; Structure-specific endonuclease subunit EME2 [-]
