    Summary
    Enables protein phosphatase regulator activity. Involved in several processes, including meiosis I; positive regulation of protein localization; and regulation of mitotic cell cycle phase transition. Located in several cellular components, including cellular bud tip; fungal-type vacuole membrane; and mating projection tip. Part of protein phosphatase type 2A complex. Human ortholog(s) of this gene implicated in Alzheimer's disease; brain disease; breast cancer; and spinocerebellar ataxia type 12. Orthologous to several human genes including PPP2R2A (protein phosphatase 2 regulatory subunit Balpha) and PPP2R2D (protein phosphatase 2 regulatory subunit Bdelta).
