Rabbit Anti-Human MUS81 polyclonal antibody for WB. 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.
