Summary Reversible phosphorylation plays an important role as a mechanism of intracellular control in eukaryotes. PPP1, a major eukaryotic Ser/Thr-protein phosphatase, acquires its specificity by interacting with different protein regulators, also known ...

Hanks-Type Serine/Threonine Protein Kinases and Phosphatases in Bacteria: Roles in Signaling and Adaptation to Various Environments [PDF]
Reversible phosphorylation is a key mechanism that regulates many cellular processes in prokaryotes and eukaryotes. In prokaryotes, signal transduction includes two-component signaling systems, which involve a membrane sensor histidine kinase and a ...

Liposomal C6 Ceramide Activates Protein Phosphatase 1 to Inhibit Melanoma Cells. [PDF]
Melanoma is one common skin cancer. In the present study, the potential anti-melanoma activity by a liposomal C6 ceramide was tested in vitro. We showed that the liposomal C6 (ceramide) was cytotoxic and anti-proliferative against a panel of human ...

Structural basis of protein phosphatase 1 regulation [PDF]
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.

Integration of a Phosphatase Cascade with the MAP Kinase Pathway provides for a Novel Signal Processing Function [PDF]
We mathematically modeled the receptor-activated MAP kinase signaling by incorporating the regulation through cellular phosphatases. Activation induced the alignment of a phosphatase cascade in parallel with the MAP kinase pathway.

Protein phosphatases 1, 2A, and 2C are protein histidine phosphatases.
Eukaryotic cellular proteins contain phosphohistidine. To search for protein histidine phosphatases, protein histidine kinase from Saccharomyces cerevisiae was used to phosphorylate histone H4 on histidine at position 75 in the H4 amino acid sequence. Incubation of the phosphorylated histone H4 with either protein phosphatase 1, 2A, or 2C resulted in ...

In human and experimental heart failure, the activity of the type 1 phosphatase is significantly increased, associated with dephosphorylation of phospholamban, inhibition of the sarco(endo)plasmic reticulum Ca(2+) transport ATPase (SERCA2a) and depressed

Microcystins: Potent xenobiotics [PDF]
Having in mind that exposure to low levels of microcystin in drinking water represents the health risk for people, microcystins can be observed as potent xenobiotics.

Background One of the major cellular serine/threonine protein phosphatases is protein phosphatase type 1 (PP1). Studies employing many eukaryotic systems all point to a crucial role for PP1 activity in controlling cell cycle progression.
