Development and validation of an expanded antibody toolset that captures alpha-synuclein pathological diversity in Lewy body diseases

Hilal Lashuel, Johannes Burtscher, Melek Firat Altay, Somanath Jagannath

The abnormal aggregation and accumulation of alpha-synuclein (aSyn) in the brain is a defining hallmark of synucleinopathies. Various aSyn conformations and post-translationally modified forms accumulate in pathological inclusions and vary in abundance amo ...

AMP-activated Protein Kinase (AMPK): New molecular insights and novel downstream targets

Katyayanee Neopane

AMP-activated Protein Kinase (AMPK) is a central regulator of energy homeostasis and a promising drug target for metabolic disorders. It exists as complexes of three subunits, a catalytic alpha, and two regulatory beta and gamma subunits. The regulation of ...

Capturing the heterogeneity of alpha-synuclein pathology in synucleinopathies

Melek Firat Altay

Synucleinopathies such as Parkinson's disease, dementia with Lewy bodies and multiple system atrophy (MSA) are detrimental neurodegenerative diseases. Alpha-synuclein (aSyn), the main aggregating protein found in the pathological inclusions of these ailmen ...

Can Precision Electrophile Signaling Make a Meaningful and Lasting Impression in Drug Design?

Yimon Aye, Amogh Kulkarni

For several years, drugs with reactive electrophilic appendages have been developed. These units typically confer prolonged residence time of the drugs on their protein targets, and may assist targeting shallow binding sites and/or improving the drug-prote ...

Phospho-S129 Alpha-Synuclein Is Present in Human Plasma but Not in Cerebrospinal Fluid as Determined by an Ultrasensitive Immunoassay

Hilal Lashuel, Sean Michael Deguire, Lara Petricca

Accumulation and aggregation of misfolded alpha-synuclein is believed to be a cause of Parkinson's disease (PD). Phosphorylation of alpha-synuclein at S129 is known to be associated with the pathological misfolding process, but efforts to investigate the r ...

Multi-phosphorylation reaction and clustering tune Pom1 gradient mid-cell levels according to cell size

Suliana Manley, Anna Archetti, Lina Carlini, Charlotte Sophia Floderer, Thaïs Reichler

Protein concentration gradients pattern developing organisms and single cells. In Schizosaccharomyces pombe rod-shaped cells, Pom1 kinase forms gradients with maxima at cell poles. Pom1 controls the timing of mitotic entry by inhibiting Cdr2, which forms s ...

Mitochondrial Post-translational Modifications and Metabolic Control: Sirtuins and Beyond

Carlos Canto Alvarez

Introduction: In order to maintain metabolic homeostasis, organisms adjust the capacity and efficiency of ATP generation to changes in energetic demand and supply. While the transcriptional control of mitochondrial biogenesis allows to adapt mitochondrial ...

Circadian and Feeding Rhythms Orchestrate the Diurnal Liver Acetylome

Felix Naef, Carlos Canto Alvarez, Jingkui Wang, Loïc Dayon, Frédéric Bruno Martin Gachon, Martin Kussmann, Daniel Alain Dominique Marie Mauvoisin, Joanna Ratajczak, Sebastiano Collino, Florian Atger

Lysine acetylation is involved in various biological processes and is considered a key reversible post-translational modification in the regulation of gene expression, enzyme activity, and subcellular localization. This post-translational modification is t ...

AMP-activated protein kinase : strategies for activation and downstream target identification

Serge Thanh Son Ducommun

AMP-activated protein kinase (AMPK) is an evolutionally conserved key sensor of cellular energy status. Under conditions of cellular energy stress, AMPK is activated and will switch off anabolic processes that consume ATP, while activating catabolic proces ...

Effect of TiO2 Nanoparticles and UV Radiation on Extracellular Enzyme Activity of Intact Heterotrophic Biofilms

Kristin Schirmer, Laura Sigg, Hannah Inka Schug

When introduced into the aquatic environment, TiO2 NP are likely to settle from the water column, which results in increased exposure of benthic communities. Here, we show that the activity of two extracellular enzymes of intact heterotrophic biofilms, bet ...

Phosphorylation Regulates FOXC2-Mediated Transcription in Lymphatic Endothelial Cells

Nadine Fournier, Mauro Delorenzi, Nawal Houhou, Yan Agalarov

One of the key mechanisms linking cell signaling and control of gene expression is reversible phosphorylation of transcription factors. FOXC2 is a forkhead transcription factor that is mutated in the human vascular disease lymphedema-distichiasis and plays ...

Exploration of trade-offs between steady-state and dynamic properties in signaling cycles

Dominique Bonvin, Vassily Hatzimanikatis, Benoît Chachuat, Andrijana Radivojevic

In the intracellular signaling networks that regulate important cell processes, the base pattern comprises the cycle of reversible phosphorylation of a protein, catalyzed by kinases and opposing phosphatases. Mathematical modeling and analysis have been us ...

Phosphorylation state defines discrete roles for monopolin in chromosome attachment and spindle elongation

Viesturs Simanis

BACKGROUND: It is unknown how oscillations in Cdk1 activity drive the dramatic changes in chromosome and spindle dynamics that occur at the metaphase/anaphase transition. RESULTS: We show that the Schizosaccharomyces pombe monopolin complex has distinct fu ...

Nouvelles approches synthétiques de prodrogues de cyclosporine A et d'analogues antiviraux

Jérémy Bérard

The cyclosporins comprise a family of cyclic 11-peptides containing seven N-methylated, hydrophobic amino acids. Cyclosporine A (CsA) representing the major member of this family is widely used as immunosuppressive agent in organ transplantations. The biol ...

Mycobacterial Ser/Thr protein kinases and phosphatases: physiological roles and therapeutic potential

Stewart Cole, Pablo Fernandez

Reversible protein phosphorylation is a major regulation mechanism of fundamental biological processes, not only in eukaryotes but also in bacteria. A growing body of evidence suggests that Ser/Thr phosphorylation play important roles in the physiology and ...

Mitotic hyperphosphorylation of the fission yeast SIN scaffold protein cdc11p is regulated by the protein kinase cdc7p

Viesturs Simanis, Andrea Krapp, Elena Cano

The fission yeast septation initiation network (SIN) triggers the onset of septum formation and cytokinesis. SIN proteins signal from the spindle pole body (SPB), to which they bind in a cell cycle-dependent manner, via the scaffold proteins sid4p and cdc1 ...
