Stress-activated protein kinases are negatively regulated by cell density.
Stimulation by UV irradiation, TNFalpha, as well as PDGF or EGF activates the JNK/SAPK signalling pathway in mouse fibroblasts. This results in the phosphorylation of the N-terminal domain of c-Jun, increasing its transactivation potency. Using an antibody that specifically recognizes c-Jun phosphorylated at Ser63, we show that culture confluency drastically inhibited c-Jun N-terminal phosphory...
متن کاملThe stress-activated protein kinases are major c-Jun amino-terminal kinases activated by ischemia and reperfusion.
The signal transduction pathways that mediate activation of trans acting factors controlling an organ's response to ischemia are unknown. The stress-activated protein kinases (SAPKs), a subfamily of the extracellular signal-regulated kinases (ERKs), phosphorylate c-Jun within the amino-terminal transactivation domain and are activated in response to a variety of cellular stresses. We determined...
متن کاملStomatal development and patterning are regulated by environmentally responsive mitogen-activated protein kinases in Arabidopsis.
Stomata are specialized epidermal structures that regulate gas (CO(2) and O(2)) and water vapor exchange between plants and their environment. In Arabidopsis thaliana, stomatal development is preceded by asymmetric cell divisions, and stomatal distribution follows the one-cell spacing rule, reflecting the coordination of cell fate specification. Stomatal development and patterning are regulated...
متن کاملMultilayered control of gene expression by stress-activated protein kinases.
Stress-activated protein kinases (SAPKs) are key elements for intracellular signalling networks that serve to respond and adapt to extracellular changes. Exposure of yeast to high osmolarity results in the activation of p38-related SAPK, Hog1, which is essential for reprogramming the gene expression capacity of the cell by regulation of several steps of the transcription process. At initiation,...
متن کامل"Stress-responsive" mitogen-activated protein kinases (c-Jun N-terminal kinases and p38 mitogen-activated protein kinases) in the myocardium.
Mitogen-Activated Protein Kinase Cascades: Terminology and Properties The best-characterized subfamilies of the mitogen-activated protein kinase (MAPK) superfamily are the extracellularly responsive kinases (ERKs) and the two “stress-responsive” MAPK subfamilies, namely, the c-Jun N-terminal kinases (JNKs) and the p38-MAPKs. As yet, no single nomenclature has been determined, and the synonyms c...
