Protein tyrosine phosphatases.
The molecular mechanisms of signal transduction have been at the focus of increasingly intense scientific research. As a result, our understanding of protein tyrosine kinase-mediated signaling has advanced at an unprecedented pace during the past decade. In contrast, the study of protein tyrosine phosphatases has lagged behind, but is now gathering momentum and is predicted to become a "hot top...
متن کاملProtein-tyrosine phosphatases in development
One of the most important mechanisms of eukaryotic signalling is protein phosphorylation on tyrosine residues, which plays a pivotal role in development by regulating cell proliferation, differentiation and migration. Cellular phosphotyrosine (P.Tyr) levels are regulated by the antagonistic activities of the protein-tyrosine kinases (PTKs) and protein-tyrosine phosphatases (PTPs). We have good ...
متن کاملHepatic protein tyrosine phosphatases in the rat.
Regulation of cell growth and metabolism by protein tyrosine phosphorylation involves dephosphorylation via the action of protein tyrosine phosphatases (PTPases). We have characterized the membrane PTPases in rat liver, monitoring their activity by measuring the dephosphorylation of P-Tyr-reduced, carboxyamidomethylated and maleylated lysozyme (P-Tyr-RCML) and P-Tyr-myelin basic protein (P-Tyr-...
متن کاملReceptor-type protein tyrosine phosphatases in cancer
Protein tyrosine phosphatases (PTPs) play an important role in regulating cell signaling events in coordination with tyrosine kinases to control cell proliferation, apoptosis, survival, migration, and invasion. Receptor-type protein tyrosine phosphatases (PTPRs) are a subgroup of PTPs that share a transmembrane domain with resulting similarities in function and target specificity. In this revie...
متن کاملProtein tyrosine phosphatases in pathological process.
Protein tyrosine phosphatases (PTPs) modulate the cellular level of tyrosine phosphorylation under normal and pathological conditions, and thus exert either stimulatory or inhibitory effect on signal transduction. Hence, PTPs are potential pharmacological targets for novel drugs being developed in order to treat numerous pathologies including cancer. For example, PTPs have been found to play a ...
