|Abstract:||The control of biological events requires strict regulation using complex protein phosphorylation and dephosphorylation strategies. The bulk of serine-threonine dephosphorylations are catalyzed by a handful of phosphatase catalytic subunits, giving rise to the misconception that these phosphatases are promiscuous and unregulated enzymes in vivo. The reality is much more nuanced: PP1 and PP2A, the most abundant serine-threonine phosphatases, are, in fact, families of hundreds of protein serine/threonine phosphatases, assembled from a few catalytic subunits in combination with a highly diverse array of regulators. As recent publications illustrate, these regulatory subunits confer specificity, selectivity, localization, and regulation on these important enzymes. © 2009 Elsevier Inc. All rights reserved.|
