Plays an important role in chromosome segregation during meiosis I by allowing meiotic rec8 to establish cohesion at the centromeric central core and thereby promote the side-by-side structure of kinetochores at meiosis I. Enables monopolar attachment during meiosis I (PubMed:16303567, PubMed:16325576). Required to facilitate kinetochore mono-orientation during meiosis I, when kinetochores on sister chromosomes face the same direction and are thus captured and pulled by spindle fibers from the same pole (PubMed:25533956). Acts in collaboration with plo1 (PubMed:25533956). Interacts with rec8 (PubMed:16325576), Interacts with plo1 (PubMed:25533956). Localizes to the centromere. Does not require rec8 for centromeric localization but instead cnp3. Present during meiotic prophase I, when monopolar attachment of kinetochores to spindle microtubules is established. First appears during prophase I and localizes to several punctate dots in the nucleus until metaphase I. At the onset of anaphase I, it decreases markedly and remains absent until telophase I. Does not reappear during meiosis II.
