Nucleotide excision repair protein ERCC1; Ercc1 (Ercc1) encodes the non-catalytic partner of the nuclease encoded by mei-9 that cuts structures formed during DNA repair. The mei-9-Ercc1 heterodimer interacts with the product of mus312 to make meiotic crossovers. The functions of the product of Ercc1 include repair of UV-induced DNA damage, repair of base adducts, a backup pathway for mismatch repair and meiotic recombination.

DNA repair endonuclease XPF; Implicated in recombination events during meiosis, mostly in meiotic exchange. May directly resolve Holliday junctions within recombination intermediates leading to DNA exchange. Also required for the repair of mismatches within meiotic heteroduplex DNA and for nucleotide excision repair.

Structure-specific endonuclease subunit SLX1 homolog; Catalytic subunit of a heterodimeric structure-specific endonuclease that resolves DNA secondary structures generated during DNA repair and recombination. Has endonuclease activity towards branched DNA substrates, introducing single-strand cuts in duplex DNA close to junctions with ss-DNA; Belongs to the SLX1 family.

DNA repair protein Rad51 homolog; Spindle A (spn-A) encodes a protein that forms a filament on single-stranded DNA, does a homology search of double-stranded DNA, and catalyzes strand exchange, swapping the single-strand DNA in and displacing the partner of the complementary strand.

Bloom syndrome helicase (Blm) encodes a protein that plays important roles in repairing replication fork damage and double-strand breaks. It promotes repair through non-crossover mechanisms, though it also has roles in meiotic recombination.

Structure-specific endonuclease subunit SLX4; Regulatory subunit that interacts with and increases the activity of different structure-specific endonucleases. Has several distinct roles in protecting genome stability by resolving diverse forms of deleterious DNA structures originating from replication and recombination intermediates and from DNA damage (By similarity). Component of the SLX1-SLX4 structure-specific endonuclease that resolves DNA secondary structures generated during DNA repair and recombination. Has endonuclease activity towards branched DNA substrates, introducing sing [...]

Exonuclease 1; 5'->3' double-stranded DNA exonuclease which may also contain a cryptic 3'->5' double-stranded DNA exonuclease activity. Also exhibits endonuclease activity against 5'-overhanging flap structures similar to those generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Required for DNA mismatch repair (MMR) (By similarity).

Fanconi anemia group M helicase (Fancm) encodes a protein that promotes repair of DNA interstrand crosslinks through the Fanconi anemia pathway and non-crossover repair of DNA double-strand breaks.

DNA topoisomerase 3-beta; Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)- enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand than undergoes passage around the unbroken strand thus removing DNA supercoils. [...]
