 219-439 1.77e-76

nuclease domain of XPF/MUS81 family proteins; The XPF/MUS81 family belongs to 3'-flap endonuclease that act upon 3'-flap structures and involved in DNA repair pathways that are necessary for the removal of UV-light-induced DNA lesions and cross-links between DNA strands. Family members exist either as heterodimers or as homodimers in their functionally competent states which consist of a catalytic and a noncatalytic subunit. The catalytic subunits have a DX(n)RKX(3)D motif. This motif is required for metal-dependent endonuclease activity but not for DNA junction binding. The equivalent regions of the noncatalytic subunits (ERCC1, EME1, and FAAP24) have diverged. The noncatalytic subunits have roles such as binding ssDNA or an ability to target the endonuclease to defined DNA structures or sites of DNA damage.

XPF-like nuclease domain of crossover junction endonuclease EME1; EME1, also called MMS4 homolog (hMMS4), interacts with MUS81 to form a DNA structure-specific endonuclease with substrate preference for branched DNA structures with a 5'-end at the branch nick. Its typical substrates include 3'-flap structures, replication forks and nicked Holliday junctions. EME1 may be required in mitosis for the processing of stalled or collapsed replication forks. The nuclease domain of EME1 is a nuclease-like domain which is involved in targeting the MUS81-EME1 heterodimer complex to DNA.
