Protein
Crossover junction endonuclease MUS81
Gene
mus81
Organism
Danio rerio (Zebrafish) (Brachydanio rerio)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

Interacts with eme1 and eme2 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 By similarity.

Cofactori

Magnesium By similarity.
