Serine/threonine-protein phosphatase 2A regulatory subunit B” subunit beta is an enzyme that in humans is encoded by the PPP2R3B gene.Protein phosphatase 2 (formerly named type 2A) is one of the four major Ser/Thr phosphatases and is implicated in the negative control of cell growth and division. Protein phosphatase 2 holoenzymes are heterotrimeric proteins composed of a structural subunit A a catalytic subunit C and a regulatory subunit B.
