Anti-Protein Serine/Threonine Phosphatase 2A/B alpha

Type 2 protein phosphatases are serine/threonine phosphatases which can preferentially dephosphorylate the alpha subunit of phosphorylase kinase and are insensitive to inhibitor 2 treatment. Protein phosphatase 2A (PP2A) can be distinguished from PP2B and PP2C which require Ca2+ and Mg2+, respectively, by its partial activity in the absence of divalent cations. PP2A activity is potently inhibited by treatment with okadaic acid and shows much stronger activity toward histone phosphorylated by Protein Kinase C and casein phosphorylated by Protein Kinase A than other protein phosphatases.
