XPF-like nuclease domain of Mus81; Mus81 is a crossover junction endonuclease that 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. The typical substrates include 3'-flap structures, replication forks and nicked Holliday junctions. Mus81 may be required in mitosis for the processing of stalled or collapsed replication forks. Mus81 consists of the active nuclease domain with the GDX(n)ERKX(3)D motif which is required for metal-dependent endonuclease activity and two helix-hairpin-helix (HhH2) domains. : Pssm-ID: 410850 [Multi-domain] Cd Length: 150 Bit Score: 236.61 E-value: 7.75e-76

winged helix domain found in crossover junction endonuclease MUS81 and similar proteins; MUS81 is a crossover junction endonuclease that interacts with EME1 (essential meiotic structure-specific endonuclease 1) and EME2, to form a DNA structure-specific endonuclease with substrate preference for branched DNA structures with a 5'-end at the branch nick. The MUS80-EME1 endonuclease maintains genomic integrity in metazoans by cleaving branched DNA structures that can form during mitosis and fission yeast meiosis, and during processing of damaged replication folks. This model corresponds to the winged helix (WH) domain of MUS81, which is responsible for DNA binding. It comprises four helices and two beta strands. : Pssm-ID: 411029 Cd Length: 94 Bit Score: 97.60 E-value: 1.55e-24

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 family DNA repair endonuclease; (Xeroderma Pigmentosum group F) DNA repair gene homologs are members of the XPF/Rad1/Mus81-dependent nuclease family which specifically cleave branched structures generated during DNA repair, replication, and recombination, and they are essential for maintaining genome stability. They belong to a wider superfamily of nucleases including very short patch repair (Vsr) endonucleases, archaeal Holliday junction resolvases, MutH methyl-directed DNA mismatch-repair endonucleases, and catalytic domains of many restriction endonucleases, such as EcoRI, BamHI, and FokI.

nuclease domain of XPF found in archaea; XPF, also called DNA excision repair protein ERCC-4, or DNA repair protein complementing XP-F cells, or Xeroderma pigmentosum group F-complementing protein, is a 3'-flap repair endonuclease that cleaves 5' of ds/ssDNA interfaces in 3' flap structures, although it also cuts bubble, Y-DNA structures and mobile and immobile Holliday junctions. XPF cuts preferentially after pyrimidines, may continue to progressively cleave substrate upstream of the initial cleavage, at least in vitro. It may be involved in nucleotide excision repair. The nuclease domains of the catalytic subunits XPF have the GDX(n)ERKX(3)D motif which is required for metal-dependent endonuclease activity but not for DNA junction binding. XPF-ERRC1 and its yeast homolog Rad1-Rad10 play key roles in the excision of DNA lesions and are required for certain types of homologous recombination events and for the repair of DNA cross-links.
