Required during the early stages of meiosis for meiotic recombination. Homomer (PubMed:31665745). Interacts (via C-terminus) with hop1 (via C-terminus); the interaction is direct (PubMed:31665745). Interacts (via C-terminus) with rec10; the interaction is direct (PubMed:31665745). Interacts with mde2; the interaction is direct (PubMed:31665745). Localizes to meiotic chromosomal axis sites and DNA double-strand break (DSB) hotspots. Abolishes localization of hop1 to DNA double-strand break (DSB) hotspots.
