Organizes linear element components on chromosomes and is thus required for meiotic DNA recombination. Component of linear elements (LinEs), which are similar to synaptonemal complexes, at least composed of rec27, rec25, rec10 and mug20 (PubMed:23395004). Interacts with rec25; the interaction is direct (PubMed:31665745). Interacts with hop1 (via N-terminus); the interaction is direct (PubMed:31665745). Interacts with rec15 (via C-terminus); the interaction is direct (PubMed:31665745). Localizes to DNA double-strand break (DSB) hotspots. Present from pre-meiotic DNA replication and disappears following meiotic prophase I. Abnormal linear element formation (PubMed:33825974, PubMed:23395004). Abolishes localization of hop1 to meiotic chromosomal axis sites and DNA double-strand break (DSB) hotspots (PubMed:31665745). Severely decreases localization of rec15 to chromosomal axis sites (PubMed:31665745). Abnormal sporulation (PubMed:33825974).
