CC -!- FUNCTION: During meiotic DNA recombination, binds to and may help
CC activate DNA double-strand break (DSB) hotspot sites.
CC {ECO:0000269|PubMed:23395004}.
CC -!- SUBUNIT: Component of linear elements (LinEs), which are similar to
CC synaptonemal complexes, at least composed of rec27, rec25, rec10 and
CC mug20 (PubMed:23395004). Interacts with rec10 (PubMed:19756689).
CC {ECO:0000269|PubMed:19756689, ECO:0000269|PubMed:23395004}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:16823372}. Nucleus

CC ECO:0000269|PubMed:33825974}. Chromosome {ECO:0000269|PubMed:23395004}.
CC Note=Localizes to chromosomal double-strand break (DSB) hotspot sites
CC during the meiotic cell cycle. {ECO:0000269|PubMed:23395004}.
CC -!- DEVELOPMENTAL STAGE: Up-regulated during meiosis (PubMed:16303567).
CC Present from pre-meiotic DNA replication and disappears following
CC meiotic prophase I (PubMed:23395004, PubMed:33825974).
CC {ECO:0000269|PubMed:16303567, ECO:0000269|PubMed:23395004,
CC ECO:0000269|PubMed:33825974}.
CC -!- DISRUPTION PHENOTYPE: Abnormal linear element formation
CC (PubMed:33825974, PubMed:23395004). Decreases meiotic gene conversion
CC at ade6 (PubMed:23395004). Decreases crossing-over between ade6 and
CC arg1, and lys4 and his4 (PubMed:23395004). Abnormal sporulation
CC (PubMed:33825974). {ECO:0000269|PubMed:23395004,
