PP2A
PP2A (Protein phosphatase 2) is an enzyme that in humans is encoded by the PPP2CA gene.[2] The PP2A heterotrimeric protein phosphatase, is a ubiquitous and conserved serine/threonine phosphatase with broad substrate specificity and diverse cellular functions. Among the targets of PP2A are proteins of oncogenic signaling cascades, such as Raf, MEK, and AKT.
