The PP2A/4/6 subfamily of phosphoprotein phosphatases regulates DAF-16 and confers resistance to environmental stress in postreproductive adult C. elegans. [PDF]
Insulin and insulin-like growth factors are longevity determinants that negatively regulate Forkhead box class O (FoxO) transcription factors. In C. elegans mutations that constitutively activate DAF-16, the ortholog of mammalian FoxO3a, extend lifespan ...

Sequence homology between purple acid phosphatases and phosphoprotein phosphatases [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. The phosphoprotein phosphatases 1, 2A and 2B are proposed to be iron‐zinc metalloenzymes with active sites isostructural

Unfair competition governs the interaction of pCPI-17 with myosin phosphatase (PP1-MYPT1)
The small phosphoprotein pCPI-17 inhibits myosin light-chain phosphatase (MLCP). Current models postulate that during muscle relaxation, phosphatases other than MLCP dephosphorylate and inactivate pCPI-17 to restore MLCP activity.

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 ...

Spontaneous AP (action potential) firing of sinoatrial nodal cells (SANC) is critically dependent on protein kinase A (PKA) and Ca2+/calmodulin-dependent protein kinase II (CaMKII)-dependent protein phosphorylation, which are required for the generation ...

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
