Meiotic regulator; involved in maintaining sister chromatid cohesion during meiosis I as well as promoting proper attachment of kinetochores to the spindle during meiosis I and meiosis II; promotes phosphorylation of Cdc5p substrates in MI and impacts Hrr25p function in MII; substrate of the anaphase-promoting complex (APC) that is degraded during anaphase I; expressed solely in meiotic cells
