[en] Reversible protein phosphorylation is a major intracellular mechanism for controlling many important physiological activities. In the past, most of the attention was focused primarily on protein kinases and on their regulation, mainly because phosphatases were then viewed as simple housekeeping enzymes. But advances in the understanding of phosphatases make now clear that protein phosphatases are dynamic and highly regulated enzymes and are as important as kinases in the regulation of cellular processes involving protein phosphorylation.
Protein phosphatase 2A (PP2A) is a very abundant -it accounts for as much as 1% of total cellular protein-, ubiquitous and remarkably conserved enzyme. By dephosphorylating a plethora of cellular proteins, it is involved in the regulation of nearly all cellular activities.
