J-domain protein chaperone circuits in proteostasis and disease

Paolo De Los Rios, Duccio Malinverni, Ruobing Zhang

The J-domain proteins (JDP) form the largest protein family among cellular chaperones. In cooperation with the Hsp70 chaperone system, these co-chaperones orchestrate a plethora of distinct functions, including those that help maintain cellular proteostasi ...

The N-Terminal Region of Yeast Protein Phosphatase Ppz1 Is a Determinant for Its Toxicity

Maria Lopez Malo

The Ppz enzymes are Ser/Thr protein phosphatases present only in fungi that are characterized by a highly conserved C-terminal catalytic region, related to PP1c phosphatases, and a more divergent N-terminal extension. In Saccharomyces cerevisiae, Ppz phosp ...

Receptor-independent modulation of cAMP-dependent protein kinase and protein phosphatase signaling in cardiac myocytes by oxidizing agents

Sonia Donzelli

The contraction and relaxation of the heart is controlled by stimulation of the beta 1-adrenoreceptor (AR) signaling cascade, which leads to activation of cAMP-dependent protein kinase (PKA) and subsequent cardiac protein phosphorylation. Phosphorylation i ...

Live imaging screen reveals that TYRO3 and GAK ensure accurate spindle positioning in human cells

Pierre Gönczy, Coralie Busso, Benita Wolf

Proper spindle positioning is crucial for spatial cell division control. Spindle positioning in human cells relies on a ternary complex comprising G alpha i1-3, LGN and NuMA, which anchors dynein at the cell cortex, thus enabling pulling forces to be exert ...

Casein kinase 2 mediated phosphorylation of Spt6 modulates histone dynamics and regulates spurious transcription

Eric Paquet

CK2 is an essential protein kinase implicated in various cellular processes. In this study, we address a potential role of this kinase in chromatin modulations associated with transcription. We found that CK2 depletion from yeast cells leads to replication ...

Notch-Induced miR-708 Antagonizes Satellite Cell Migration and Maintains Quiescence

Joao Pedro Bronze de Firmino

Critical features of stem cells include anchoring within a niche and activation upon injury. Notch signaling maintains skeletal muscle satellite (stem) cell quiescence by inhibiting differentiation and inducing expression of extracellular components of the ...

Structural and functional analysis of host attachment proteins from contractile injection systems

Michel Plattner

Bacteriophages of the myoviridae family, R-type pyocin, Photorhabus virulence cassette (PVC), Serratia antifeeding prophage (Afp) and type 6 secretion system (T6SS) form a class of contractile injection systems that share common structural and functional c ...

The Multi-kinase Inhibitor Debio 0617B Reduces Maintenance and Self-renewal of Primary Human AML CD34(+) Stem/Progenitor Cells

Michel Aguet, Stefania Rigotti, Maximilien Murone, Andres McAllister

Acute myelogenous leukemia (AML) is initiated and maintained by leukemia stem cells (LSC). LSCs are therapy-resistant, cause relapse, and represent a major obstacle for the cure of AML. Resistance to therapy is often mediated by aberrant tyrosine kinase (T ...

Allosteric regulation and targeting of Abl SH2-kinase interface and other cytoplasmic tyrosine kinases

Allan Joaquim Lamontanara

Due to their central role in normal cellular physiology, the activity of protein kinases is tightly regulated and their aberrant activation can lead to cancer. Chronic myelogenous leukemia (CML) is a blood cancer characterized by unregulated growth of myel ...

Identification of genetic interactors of ypa2 in Schizosaccharomyces pombe

Manuela Moraru

In this study, the fission yeast Schizosaccharomyces pombe was used as a model system to study the cellular signaling that underlies cell cycle progression. Phosphorylation plays an important part in the regulation of this process. Kinases catalyze the tra ...

Functional Perturbation of the Gab2 Multiprotein Complex by High-affinity SH2-binding Monobodies in Chronic Myelogenous Leukemia

Emel Basak Gencer Akçok

Chronic myeloid leukemia is characterized by a reciprocal chromosomal translocation between chromosome 9 and 22, resulting in the expression of the Bcr-Abl oncoprotein. Despite the great improvement in patient survival using tyrosine kinase inhibitors (TKI ...

Somatic and axonal LIGHT signaling elicit degenerative and regenerative responses in motoneurons, respectively

Julianne Bobela

A receptor-ligand interaction can evoke a broad range of biological activities in different cell types depending on receptor identity and cell type-specific post-receptor signaling intermediates. Here, we show that the TNF family member LIGHT, known to act ...
