Molecular Evolution of Phosphoprotein Phosphatases in Drosophila [PDF]
PLoS ONE, 2011 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]
STAR Protocols, 2023 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.

Unfair competition governs the interaction of pCPI-17 with myosin phosphatase (PP1-MYPT1) [PDF]
eLife, 2017 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.

PHOSPHORYLATION/DEPHOSPHORYLATION OF MITOCHONDRIAL PROTEINS IN REDOX-SIGNALLING OF HIGHER PLANTS UNDER ABIOTIC STRESS CONDITIONS [PDF]
Journal of Stress Physiology & Biochemistry, 2012 We studied an impact of the widely spread intra-cellular signals Ca2+ and сAMP on activity of the protein phosphorylation in maize mitochondria. The use of the isolated mitochondria is a convenient model system for investigation of the different ...

Life, 2021 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 ...

Phosphatase specificity principles uncovered by MRBLE:Dephos and global substrate identification
Molecular Systems Biology, 2023 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.
