PPP2R2A (An enzyme regulator in humans) consist of a common heteromeric core enzyme, and it is implicated in the negative control of cell growth.
Serine/threonine-protein phosphatase 2A 55 kDa regulatory subunit B alpha isoform is an enzyme regulator that in humans is encoded by the PPP2R2A gene. 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.
