Facilitates initiation of meiotic recombination and DNA double-strand break (DSB) formation at DSB hotspot sites by enhancing the interaction between rec10 and rec15. Interacts (via N-terminus) with rec10; the interaction is direct (PubMed:31665745). Interacts (via C-terminus) with rec15 (via C-terminus); the interaction is direct (PubMed:31665745). Predominantly localizes to linear elements (LinEs) on meiotic chromosomes, the S.pombe equivalents of synaptonemal complexes. A proportion also localizes to DNA double-strand break (DSB) hotspots. Present from pre-meiotic DNA replication and throughout meiosis I. Decreases DNA double-strand break formation during meiosis and meiotic gene conversion at ade6 (PubMed:31665745). Decreases localization of rec15 and rec10 to DNA double strand break (DSB) hotspots, and decreases localization of rec15 to chromosomal axis sites (PubMed:31665745). Abnormal sporulation (PubMed:33825974).
