Serin/treonin proteinska fosfataza 2A katalitička podjedinica alfa izoforma je enzim koji je kod ljudi kodiran PPP2CA genom.[1]
Proteinska fosfataza 2A je jedna od četiri glavne Ser/Thr fosfataze. Ona učestvuje u negativnoj kontroli ćelijskog rasta i deobe. Ona se sastoji od heteromerne enzimske osnove, koji ima katalitičku i konstantnu regulatornu podjedinicu, za koji se vezuje niz regulatornih podjedinica. Ovaj gen kodira alfa izoformu katalitičke podjedinice.[2]
