Hyperphosphatemia, Phosphoprotein Phosphatases, and Microparticle Release in Vascular Endothelial Cells. [PDF]
Hyperphosphatemia in patients with advanced CKD is thought to be an important contributor to cardiovascular risk, in part because of endothelial cell (EC) dysfunction induced by inorganic phosphate (Pi).

Use of intein-mediated phosphoprotein arrays to study substrate specificity of protein phosphatases
Synthetic peptides incorporating various chemical moieties, for example, phosphate groups, are convenient tools for investigating protein modification enzymes, such as protein phosphatases (PPs). However, short peptides are sometimes poor substrates, and

Coordination of Protein Kinase and Phosphoprotein Phosphatase Activities in Mitosis
Dynamic changes in protein phosphorylation govern the transitions between different phases of the cell division cycle. A “tug of war” between highly conserved protein kinases and the family of phosphoprotein phosphatases (PPP) establishes the ...

Phosphatase ABI1 and okadaic acid-sensitive phosphoprotein phosphatases inhibit salt stress-activated SnRK2.4 kinase. [PDF]
Background: SNF1-related protein kinases 2 (SnRK2s) are key regulators of the plant response to osmotic stress. They are transiently activated in response to drought and salinity. Based on phylogenetic analysis SnRK2s are divided into three groups.

Phosphatase specificity principles uncovered by MRBLE:Dephos and global substrate identification
Phosphoprotein phosphatases (PPPs) regulate major signaling pathways, but the determinants of phosphatase specificity are poorly understood. This is because methods to investigate this at scale are lacking.

Sequence homology between purple acid phosphatases and phosphoprotein phosphatases Are phosphoprotein phosphatases metalloproteins containing oxide-bridged dinuclear metal centers? [PDF]
The amino acid sequences of mammalian purple acid phosphatases and phosphoprotein phosphatases are shown to possess regions of significant homology. The conserved residues contain a high percentage of possible metal-binding residues.
