Mus81

Protein FULL name:

crossover junction endonuclease MUS81 [Mus musculus].


Mus81 (Mus musculus) is product of expression of Mus81 gene.






FUNCTION: 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.

COFACTOR: Magnesium.

SUBUNIT: May self-associate. Interacts with CHEK2. Interacts with BLM, and this interaction may stimulate the endonuclease activity of MUS81. Interacts with EME2. Interacts with BTBD12/SLX4; this interaction is direct and links the MUS81-EME1 complex to SLX4, which may coordinate the action of the structure-specific endonuclease during DNA repair (By similarity). Interacts with. EME1.

SUBCELLULAR LOCATION: Nucleus, nucleolus. Note=Recruited to foci of DNA damage in S-phase cells (By similarity).

SIMILARITY: Belongs to the XPF family.

SIMILARITY: Contains 1 ERCC4 domain.
