CC -!- FUNCTION: Endonuclease which, in association with baf-1, plays an
CC essential role during embryogenesis in the DNA repair response
CC following DNA damage probably by ensuring proper chromosome segregation
CC (PubMed:22383942). Also required during postembryonic cell divisions
CC after DNA damage caused by ionizing radiation to ensure normal cell
CC proliferation (PubMed:22383942). Resolves chromatin bridges in late
CC mitosis that result from incomplete DNA replication, defective
CC chromosome condensation or unresolved recombination intermediates
CC (PubMed:29463814). Together with brc-1, contributes to genome integrity
CC by resolving mitotic chromatin bridges that result from incomplete
CC processing of DNA breaks (PubMed:29463814). In parallel to the slx-
CC 1/mus-81 pathway, acts in processing early recombination intermediates
CC in meiotic prophase I to prevent illegitimate recombination
CC (PubMed:29879106). Also involved in processing remaining, erroneous
CC recombination intermediates that persist into the second meiotic
CC division (PubMed:29879106). {ECO:0000269|PubMed:22383942,
CC ECO:0000269|PubMed:29463814, ECO:0000269|PubMed:29879106}.
CC -!- ACTIVITY REGULATION: Inhibited by EDTA. {ECO:0000269|PubMed:22383942}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:22383942,
CC ECO:0000269|PubMed:29463814, ECO:0000269|PubMed:29879106}. Nucleus
CC {ECO:0000269|PubMed:29879106}. Chromosome
CC {ECO:0000269|PubMed:29463814}. Midbody {ECO:0000269|PubMed:29463814}.
CC Cytoplasm, cytoskeleton, spindle {ECO:0000269|PubMed:29463814}.
CC Note=Localizes to foci-like structures outside the nucleus
CC (PubMed:22383942, PubMed:29463814, PubMed:29879106). In pachytene,
CC localizes to foci both in and outside of the nucleus (PubMed:29879106).
CC Colocalizes with air-2 between dividing nuclei in meiosis II
CC (PubMed:29879106). In mitosis, localizes to the center of chromatin
CC bridges that are formed in response to DNA defects (PubMed:29463814).
CC Forms initially a ring like structure encircling chromatin bridges
CC between two separated daughter cells until in late telophase, localizes
CC to the center of chromatin bridges (PubMed:29463814). Colocalizes with
CC air-2 at the midbody (PubMed:29463814). Midbody localization depends on
CC the formation of the central spindle and the midbody and on air-2
CC (PubMed:29463814). Colocalizes with the central spindle component zen-4
CC at the central spindle (PubMed:29463814). {ECO:0000269|PubMed:22383942,

CC -!- DEVELOPMENTAL STAGE: Expressed in embryos.
CC {ECO:0000269|PubMed:22383942, ECO:0000269|PubMed:29463814}.
CC -!- PTM: Phosphorylated. Phosphorylated during telophase when localized at
CC the midbody. {ECO:0000269|PubMed:29463814}.
