The role of NFAT transcription factors in integrin-mediated carcinoma invasion. (2002)

Jauliac, Sebastien, Lopez-Rodriguez, Cristina, Shaw, Leslie, Brown, Lawrence, Rao, Anjana, Toker, Alex

Integrins, receptors for extracellular matrix ligands, are critical regulators of the invasive phenotype. Specifically, the alpha(6)beta(4) integrin has been linked with epithelial cell motility,...

Identification of a novel pathway important for proliferation and differentiation of primary erythroid progenitors

Klingmüller, Ursula, Wu, Hong, Hsiao, Jonathan G., Toker, Alex, Duckworth, Brian C., Cantley, Lewis C., ...

Homodimerization of the erythropoietin (EPO) receptor (EPO-R) in response to EPO binding transiently activates the receptor-associated protein tyrosine kinase JAK2. Tyrosine phosphorylation of the...

p70 S6 Kinase Is Regulated by Protein Kinase Cζ and Participates in a Phosphoinositide 3-Kinase-Regulated Signalling Complex

Romanelli, Angela, Martin, Kathleen A., Toker, Alex, Blenis, John

p70 S6 kinase (p70S6K) is an important regulator of cell proliferation. Its activation by growth factor requires phosphorylation by various inputs on multiple sites. Data accumulated thus far support...

Protein kinase D mediates a stress-induced NF-κB activation and survival pathway

Storz, Peter, Toker, Alex

The activation of the transcription factor NF-κB is critical for a number of physiological responses. Here, we provide evidence for a signaling pathway that mediates NF-κB activation in response to...

A PDK1 homolog is necessary and sufficient to transduce AGE-1 PI3 kinase signals that regulate diapause in Caenorhabditis elegans

Paradis, Suzanne, Ailion, Michael, Toker, Alex, Thomas, James H., Ruvkun, Gary

An insulin receptor-like signaling pathway regulates Caenorhabditis elegans metabolism, development, and longevity. Inactivation of the insulin receptor homolog DAF-2, the AGE-1 PI3K, or the AKT-1...

Protein Kinase Cδ Selectively Regulates Protein Kinase D-Dependent Activation of NF-κB in Oxidative Stress Signaling

Storz, Peter, Döppler, Heike, Toker, Alex

Protein kinase D (PKD) participates in activation of the transcription factor NF-κB (nuclear factor κB) in cells exposed to oxidative stress, leading to increased cellular survival. We previously...

Functional dichotomy of A20 in apoptotic and necrotic cell death

Storz, Peter, Döppler, Heike, Ferran, Christiane, Grey, Shane T., Toker, Alex

ROS (reactive oxygen species) play important roles in the progression of a number of human pathologies. ROS promote cell death, but can also induce gene transcription. The transcription factor NF-κB...

Regulation of novel protein kinase C epsilon by phosphorylation.

Cenni, Vittoria, Döppler, Heike, Sonnenburg, Erica D, Maraldi, Nadir, Newton, Alexandra C, Toker, Alex

The activity and intracellular localization of protein kinase C (PKC) family members are controlled by phosphorylation at three highly conserved sites in the catalytic kinase domain. In the case of...

Protein Kinase D Mediates Mitochondrion-to-Nucleus Signaling and Detoxification from Mitochondrial Reactive Oxygen Species†

Storz, Peter, Döppler, Heike, Toker, Alex

Efficient elimination of mitochondrial reactive oxygen species (mROS) correlates with increased cellular survival and organism life span. Detoxification of mitochondrial ROS is regulated by induction...

The biology and biochemistry of diacylglycerol signalling

Toker, Alex

Meeting on Molecular Advances in Diacylglycerol Signalling

Protein kinase D regulates vesicular transport by phosphorylation and activation of phosphatidylinositol-4 kinase III β at the Golgi complex

Hausser, Angelika, Märtens, Susanne, Link, Gisela, Pfizenmaier, Klaus, Storz, Peter, Toker, Alex

Protein kinase D (PKD) regulates the fission of vesicles from the trans-Golgi-network1,2. We show that phosphatidylinositol-4-kinase III beta (PI4KIIIβ), a key player in Golgi complex structure and...

Protein Kinase C–Dependent Mobilization of the α6β4 Integrin from Hemidesmosomes and Its Association with Actin-Rich Cell Protrusions Drive the Chemotactic Migration of Carcinoma Cells

Rabinovitz, Isaac, Toker, Alex, Mercurio, Arthur M.

We explored the hypothesis that the chemotactic migration of carcinoma cells that assemble hemidesmosomes involves the activation of a signaling pathway that releases the α6β4 integrin from these...

Phosphorylation of the Par-1 polarity kinase by protein kinase D regulates 14-3-3 binding and membrane association

Watkins, Janis L., Lewandowski, Katherine T., Meek, Sarah E. M., Storz, Peter, Toker, Alex, Piwnica-Worms, Helen

The Par-1 protein kinases are conserved from yeast to humans, where they function as key polarity determinants. The mammalian Par-1 family is comprised of 4 members (Par-1a, -b, -c, and -d)....
