LRSAM1-mediated ubiquitylation is disrupted in axonal Charcot-Marie-Tooth disease 2P

Vincenzo Sorrentino

Charcot-Marie-Tooth (CMT) disease type 2 is a genetically heterogeneous group of inherited neuropathies characterized by motor and sensory deficits as a result of peripheral axonal degeneration. We recently reported a frameshift (FS) mutation in the Really ...

Heterochromatin protein 1 recruitment and chromatin conformational dynamics at the single-molecule level

Sinan Kilic

Chromatin is the template on which DNA-associated transactions take place in eukaryotic organisms. Nucleosomes consisting of the four histones H2A, H2B, H3 and H4 each organize ~150bp of DNA and constitute a first layer of chromatin. The three-dimensional ...

Parkin functionally interacts with PGC-1 proportional to to preserve mitochondria and protect dopaminergic neurons

Johan Auwerx, Patrick Aebischer, Bernard Schneider, Graham Knott, Norman Lionel Moullan, Davide D'Amico, Nathalie Marie Géraldine Bernard, Lu Zheng

To understand the cause of Parkinson's disease (PD), it is important to determine the functional interactions between factors linked to the disease. Parkin is associated with autosomal recessive early-onset PD, and controls the transcription of PGC-1a, a m ...

Mutant Exon1 Huntingtin Aggregation is Regulated by T3 Phosphorylation-Induced Structural Changes and Crosstalk between T3 Phosphorylation and Acetylation at K6

Giovanni Dietler, Hilal Lashuel, Francesco Simone Ruggeri, Anass Chiki, Sean Michael Deguire, Urszula Beata Cendrowska, Ritwik Burai, Annalisa Ansaloni, Sophie Vieweg

Herein, we used protein semisynthesis to investigate, for the first time, the effect of lysine acetylation and phosphorylation, as well as the crosstalk between these modifications on the structure and aggregation of mutant huntingtin exon1 (Httex1). Our r ...

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

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 effect of the functional interaction between PGC-1α and Parkin on mitochondrial quality control in Parkinson's disease

Lu Zheng

Although several genetic factors have been directly associated to Parkinsonâ s disease (PD), no single pathway has emerged to explain the etiology of this neurodegenerative disease. To further understand the cause of Parkinsonâ s disease (PD), it is ther ...

Folding and Endocytosis of Anthrax Toxin Receptors

Sarah Elisabeth Sandoz

Bacillus anthracis is the causative agent of the infectious disease anthrax. The disease is caused after taking up the spores by either inhalation, ingestion or through skin lesion. They then germinate inside the body and start secreting the tripartite ant ...

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 ...

Internalization and vacuolar targeting of the brassinosteroid hormone receptor BRI1 are regulated by ubiquitination

Florence Pojer

Brassinosteroids are plant steroid hormones that control many aspects of plant growth and development, and are perceived at the cell surface by the plasma membrane-localized receptor kinase BRI1. Here we show that BRI1 is post-translationally modified by K ...
