Claim: PPP2R2A consist of a common heteromeric core enzyme, and it is implicated in the negative control of cell growth.
Evidence: It consists of a common heteromeric core enzyme, which is composed of a catalytic subunit and a constant regulatory subunit, that associates with a variety of regulatory subunits. Protein phosphatase 2 is one of the four major Ser/Thr phosphatases, and it is implicated in the negative control of cell growth and division.
