Biochemical and biophysical characterization of ruthenation of BRCA1 RING protein by RAPTA complexes and its E3 ubiquitin ligase activity

Paul Joseph Dyson, Laure Menin, Luc Patiny

RAPTA compounds, ([Ru(eta(6)-arene)(PTA)Cl-2], PTA = 1,3,5-triaza-7-phosphaadamantane), have been reported to overcome drug resistance in cisplatin resistant cells. However, the exact mechanism of these complexes is still largely unexplored. In this study, ...

Glycation potentiates α-synuclein-associated neurodegeneration in synucleinopathies

Hilal Lashuel, Magdalena Zweckstetter, Michael Heinrich

α-Synuclein misfolding and aggregation is a hallmark in Parkinson's disease and in several other neurodegenerative diseases known as synucleinopathies. The toxic properties of α-synuclein are conserved from yeast to man, but the precise underpinnings of th ...

Cytoplasmic Ubiquitin-Specific Protease 19 (USP19) Modulates Aggregation of Polyglutamine-Expanded Ataxin-3 and Huntingtin through the HSP90 Chaperone

Françoise Gisou van der Goot Grunberg

Ubiquitin-specific protease 19 (USP19) is one of the deubiquitinating enzymes (DUBs) involved in regulating the ubiquitination status of substrate proteins. There are two major isoforms of USP19 with distinct C-termini; the USP19_a isoform has a transmembr ...

Five Questions (with their Answers) on ER-Associated Degradation

Maurizio Molinari

Production of a functional proteome is a major burden for our cells. Native proteins operate inside and outside the cells to eventually warrant life and adaptation to metabolic and environmental changes, there is no doubt that production and inappropriate ...

Ubiquitin-dependent folding of the Wnt signaling coreceptor LRP6

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Béatrice Kunz, Michal Feldman Elmalam, Elsa Anne Perrody

Many membrane proteins fold inefficiently and require the help of enzymes and chaperones. Here we reveal a novel folding assistance system that operates on membrane proteins from the cytosolic side of the endoplasmic reticulum (ER). We show that folding of ...

The Oxygen Sensor PHD2 Controls Dendritic Spines and Synapses via Modification of Filamin A

Michele Giugliano

Neuronal function is highly sensitive to changes in oxygen levels, but how hypoxia affects dendritic spine formation and synaptogenesis is unknown. Here we report that hypoxia, chemical inhibition of the oxygen-sensing prolyl hydroxylase domain proteins (P ...

ESCRT proteins restrict constitutive NF-kappa B signaling by trafficking cytokine receptors

Because signaling mediated by the transcription factor nuclear factor kappa B (NF-kappa B) is initiated by ligands and receptors that can undergo internalization, we investigated how endocytic trafficking regulated this key physiological pathway. We deplet ...

The lipidome associated with the gamma-secretase complex is required for its integrity and activity

Henning Paul-Julius Stahlberg, Patrick Fraering, Hermeto Gerber, Guillermo Miguel Garcia Osuna

gamma-Secretase is a multi-subunit membrane protease complex that catalyses the final intramembrane cleavage of the beta-amyloid precursor protein (APP) during the neuronal production of amyloid-beta peptides (A beta), which are implicated as the causative ...

Physically based models to study the alkali-silica reaction

Karen Scrivener, Cyrille Dunant

The Laboratory of Construction Materials in Lausanne has been studying the alkali-silica reaction for more than 10 years, advancing the understanding of the reaction, and also producing microstructural models which can be used to predict quantitatively the ...

Alpha-Synuclein as a Mediator in the Interplay between Aging and Parkinson's Disease

Patrick Aebischer, Bernard Schneider, Wojciech Janusz Bobela

Accumulation and misfolding of the alpha-synuclein protein are core mechanisms in the pathogenesis of Parkinson's disease. While the normal function of alpha-synuclein is mainly related to the control of vesicular neurotransmission, its pathogenic effects ...
