Regulation of signal duration and the statistical dynamics of kinase activation by scaffold proteins [PDF]

open access: yesPLoS Comput Biol. 2008 Jun 27;4(6):e1000099, 2008
Scaffolding proteins that direct the assembly of multiple kinases into a spatially localized signaling complex are often essential for the maintenance of an appropriate biological response. Although scaffolds are widely believed to have dramatic effects on the dynamics of signal propagation, the mechanisms that underlie these consequences are not well ...

Kinase Activity Profiling of Gram-Negative Pneumonia [PDF]

open access: yes, 2011
Pneumonia is a severe disease with high morbidity and mortality. A major causative pathogen is the Gram-negative bacterium Klebsiella (K.) pneumoniae. Kinases play an integral role in the transduction of intracellular signaling cascades and regulate a ...

Multiple roles of the mitogen‐activated protein kinase kinase/mitogen‐activated protein kinase cascade in Xenopus laevis [PDF]

open access: yesDevelopment, Growth & Differentiation, 1996
Mitogen‐activated protein kinase (MAPK) was originally identified as a serine/threonine protein kinase that is rapidly activated in response to various growth factors and tumor promoters in mammalian cultured cells. The kinase cascade including MAPK and its direct activator, MAPK kinase (MAPKK), is now believed to transmit various extracellular signals

Autophagic cell death associated to Sorafenib in renal cell carcinoma is mediated through Akt inhibition in an ERK1/2 independent fashion. [PDF]

open access: yesPLoS ONE, 2018
OBJECTIVES:To fully clarify the role of Mitogen Activated Protein Kinase in the therapeutic response to Sorafenib in Renal Cell Carcinoma as well as the cell death mechanism associated to this kinase inhibitor, we have evaluated the implication of ...

Revealing phosphorylation regulatory networks during embryogenesis of honey bee worker and drone (Apis mellifera)

open access: yesFrontiers in Cell and Developmental Biology, 2022
Protein phosphorylation is known to regulate a comprehensive scenario of critical cellular processes. However, phosphorylation-mediated regulatory networks in honey bee embryogenesis are mainly unknown.

Immunolocalization of dually phosphorylated MAPKs in dividing root meristem cells of Vicia faba, Pisum sativum, Lupinus luteus and Lycopersicon esculentum [PDF]

open access: yes, 2015
Key message In plants, phosphorylated MAPKs display constitutive nuclear localization; however, not all studied plant species show co-localization of activated MAPKs to mitotic microtubules.

Resolving the binding-kinase discrepancy in bacterial chemotaxis: A nonequilibrium allosteric model and the role of energy dissipation [PDF]

open access: yesProc. Natl. Acad. Sci. U.S.A. 120, e2303115120 (2023), 2023
The Escherichia coli chemotaxis signaling pathway has served as a model system for studying the adaptive sensing of environmental signals by large protein complexes. The chemoreceptors control the kinase activity of CheA in response to the extracellular ligand concentration and adapt across a wide concentration range by undergoing methylation and ...

Regulation of the JNK pathway by TGF-beta activated kinase 1 in rheumatoid arthritis synoviocytes. [PDF]

open access: yes, 2007
c-Jun N-terminal kinase (JNK) contributes to metalloproteinase (MMP) gene expression and joint destruction in inflammatory arthritis. It is phosphorylated by at least two upstream kinases, the mitogen-activated protein kinase kinases (MEK) MKK4 and MKK7,

Mitogen-activated protein kinases in atherosclerosis

open access: yesPostępy Higieny i Medycyny Doświadczalnej, 2014
Intracellular signalling cascades, in which MAPK (mitogen-activated protein kinases) intermediate, are responsible for a biological response of a cell to an external stimulus. MAP kinases, which include ERK1/2 (extracellular signalling-regulated kinase), JNK (c-Jun N-terminal kinase) and p 38 MAPK, regulate the activity of many proteins, enzymes and ...
