Protein phosphatase 2A (PP2A) comprises a family of serine/threonine phosphatases,
minimally containing a well conserved catalytic subunit, the activity of which is highly …

▪ Abstract Eukaryotic protein phosphatases are structurally and functionally diverse enzymes
that are represented by three distinct gene families. Two of these, the PPP and PPM families …

Two potent heat-stable protein phosphatase 2A (PP2A) inhibitor proteins designated I 1
PP2A and I 2 PP2A have been purified to apparent homogeneity from extracts of bovine …

INTRODUCTION Phosphorylation of structural and regulatory proteins is a major
intracellular control mechanism in eukaryotes. The phosphoryl-ation state of a protein is a …

The dephosphorylation of proteins on their serine, threonine and tyrosineresidues is
catalysed by three families of protein phosphatases that regulate numerous intracellular …

Dynamic phosphorylation and dephosphorylation of proteins are fundamental mechanisms
utilized by cells to transduce signals. Whereas transduction by protein kinases has been a …

Revised Manuscript Received November 8, 1994® abstract: Two heat-stable
proteininhibitors of protein phosphatase 2A (PP2A), tentatively designated IiPP2A and …

This review deals with the influence of serine/threonine-specific protein phosphatases on
the function of ion channels in the plasma membrane of excitable tissues. Particular focus is …

Protein phosphatase 2A (PP2A) is a family of multifunctional serine/threonine phosphatases
all composed of a catalytic C, a structural A, and a regulatory B subunit. Assembly of the …

Abstract Phosphoprotein phosphatase 2A (PP2A) is a major phosphoserine/threonine
protein phosphatase in all eukaryotes. It has been isolated as a heterotrimeric holoenzyme …
