DNA + H2O Homo sapiens in contrast to GEN1, MUS81-EME1 cleaves intact Holliday junctions poorly (preferring nicked Holliday junctions, 3'-flaps, and replication fork structures as its DNA substrates). SLX1-SLX4 and MUS81-EME1 cooperatively cleave Holliday junctions by a nick and counter-nick mechanism hydrolyzed DNA

General Information

General Information Comment Organism
malfunction the absence of SLX4 and BLM, or SLX4 and GEN1, is synthetically lethal in undamaged human cells Homo sapiens
physiological function BLM, SLX4, MUS81, and GEN1 cooperate in replication fork maintenance. BTR, SLX-MUS, and GEN1 are important for chromosome stability and faithful chromosome segregation Homo sapiens
