Role of Plastid Protein Phosphatase TAP38 in LHCII Dephosphorylation and Thylakoid Electron Flow [PDF]
, 2010 Short-term changes in illumination elicit alterations in thylakoid protein phosphorylation and reorganization of the photosynthetic machinery. Phosphorylation of LHCII, the light-harvesting complex of photosystem II, facilitates its relocation to ...

Dexamethasone-Induced Expression of Endothelial Mitogen-Activated Protein Kinase Phosphatase-1 Involves Activation of the Transcription Factors Activator Protein-1 and 3',5'-Cyclic Adenosine 5'-Monophosphate Response Element-Binding Protein and the Generation of Reactive Oxygen Species [PDF]
, 2008 We have recently identified the MAPK phosphatase (MKP)-1 as a novel mediator of the antiinflammatory properties of glucocorticoids (dexamethasone) in the human endothelium. However, nothing is as yet known about the signaling pathways responsible for the

Protein tyrosine phosphatase TbPTP1:A molecular switch controlling life cycle differentiation in trypanosomes [PDF]
, 2006 Differentiation in African trypanosomes (Trypanosoma brucei) entails passage between a mammalian host, where parasites exist as a proliferative slender form or a G0-arrested stumpy form, and the tsetse fly.

Structural basis of protein phosphatase 1 regulation [PDF]
Nature, 2004 The coordinated and reciprocal action of serine/threonine (Ser/Thr) protein kinases and phosphatases produces transient phosphorylation, a fundamental regulatory mechanism for many biological processes. The human genome encodes a far greater number of Ser/Thr protein kinases than of phosphatases.

Analysis of the structure and function of protein phosphatase 2A [PDF]
, 2004 One of the hallmarks of a living organism is the ability to respond to intra- or extracellular changes. These responses involve panoply of enzymes mediating signals through the cell and regulating distinct cellular functions.

Protein phosphatase 1 β paralogs encode the zebrafish myosin phosphatase catalytic subunit.
PLoS ONE, 2013 BackgroundThe myosin phosphatase is a highly conserved regulator of actomyosin contractility. Zebrafish has emerged as an ideal model system to study the in vivo role of myosin phosphatase in controlling cell contractility, cell movement and epithelial ...

Effects of Newly Synthesized DCP-LA-Phospholipids on Protein Kinase C and Protein Phosphatases
Cellular Physiology and Biochemistry, 2013 Background/Aims: The linoleic acid derivative DCP-LA selectively activates PKCε and inhibits protein phosphatase 1 (PP1). In the present study, we have newly synthesized phosphatidyl-ethanolamine, -serine, -choline, and -inositol containing DCP-LA at the
