Component of the BTR double Holliday Junction dissolution complex, which is involved in homologous recombination during meiotic double strand break repair in the germline (Probable). Promotes top-3 binding to double Holliday junctions (DHJ) and hence stimulates top-3-mediated dissolution (By similarity). Stabilizes and positively regulates the localization of the BTR double Holliday Junction dissolution complex components rmif-2 and him-6 at nuclear foci during meiotic recombination (PubMed:27011106, PubMed:34252074). Plays a role in double strand break repair by regulating the accumulation of rad-51 at double strand breaks during meiosis (PubMed:27011106). Positively regulates chiasma formation and DNA crossover designation, formation and positioning on chromosome arms (away from the chromosome center) during meiotic homologous recombination (PubMed:27011106, PubMed:34252074). Specifically localizes him-6 to DNA crossover sites along chromosome arms (PubMed:27011106). Also plays a role in the repair of non-crossover homologous recombination intermediates during meiosis (PubMed:27011106). Not required for chromosome pairing and synapsis (PubMed:27011106).
