Molecular Evolution of Phosphoprotein Phosphatases in Drosophila [PDF]
Phosphoprotein phosphatases (PPP), these ancient and important regulatory enzymes are present in all eukaryotic organisms. Based on the genome sequences of 12 Drosophila species we traced the evolution of the PPP catalytic subunits and noted a ...

Protocol to assess substrate dephosphorylation by serine/threonine phosphoprotein phosphatases in vitro [PDF]
Summary: Serine/threonine protein phosphatase 2 (PP2A) forms heterotrimeric holoenzymes, where a scaffold subunit bridges the PP2A catalytic subunit to a B regulatory subunit, e.g., B55α.

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 ...

Holding the PP2A and PP4 protein phosphatases at bay: emerging roles of FBXO42 and CCDC6 [PDF]
The Ser/Thr phosphoprotein phosphatases (PPPs, PP1-PP7) are major regulators of phospho-dependent signaling and precise regulation of their activity is essential for cellular homeostasis (Nilsson, 2019).

A functional map of phosphoprotein phosphatase regulation identifies an evolutionarily conserved reductase for the catalytic metal ions [PDF]
Serine/threonine phosphoprotein phosphatases (PPPs) are conserved metalloenzymes and key regulators of intracellular signaling. Here, we systematically map the components and residues required for PP2A-like phosphatase (PP2A/PP4/PP6) function using ...

Protein phosphorylation is one of the most widely observed and important post-translational modification (PTM) processes. Protein phosphorylation is regulated by protein kinases, each of which covalently attaches a phosphate group to an amino acid side ...
