Toward a unified scoring function for native state discrimination and drug-binding pocket recognition

Protein folding and receptor–ligand recognition are fundamental processes for any living organism. Although folding and ligand recognition are based on the same chemistry, the existing empirical scoring functions target just one problem: predicting the cor ...

The Chaperone and Redox Properties of CnoX Chaperedoxins Are Tailored to the Proteostatic Needs of Bacterial Species

Camille Véronique Bernadette Goemans

Hypochlorous acid (bleach), an oxidizing compound produced by neutrophils, turns the Escherichia coli chaperedoxin CnoX into a powerful holdase protecting its substrates from bleach-induced aggregation. CnoX is well conserved in bacteria, even in non-infec ...

Regulation of Endoplasmic Reticulum Architecture by Protein S-Palmitoylation

Patrick Alain Sandoz

The endoplasmic reticulum (ER) is the largest organelle in mammalian cells. More than 50 years ago, its morphology was already described as consisting of two major compartments: the rough ER and the smooth ER, which both fulfil precise and distinct functio ...

Nanocapillaries combined with optical tweezers as a single molecule technique for studying DNA-protein complexes

Roman Bulushev

Interactions of proteins with DNA are essential for carrying out DNA's biological functions and performing a cellular cycle. Such processes as DNA replication, expression and repair are performed by an organised action of various proteins. To better unders ...

Molecular chaperones inject energy from ATP hydrolysis into the non-equilibrium stabilisation of native proteins

Paolo De Los Rios, Alessandro Barducci, Pierre Goloubinoff, Bruno Claude Daniel Fauvet, Alberto Stefano Sassi

Protein homeostasis, namely the ensemble of cellular mechanisms collectively controlling the activity, stability and conformational states of proteins, depends on energy-consuming processes. De novo protein synthesis requires ATP hydrolysis for peptide bon ...

Phosphorylation of huntingtin at residue T3 is decreased in Huntington’s disease and modulates mutant huntingtin protein conformation

Hilal Lashuel, Lara Petricca, Anass Chiki, Sean Michael Deguire

Posttranslational modifications can have profound effects on the biological and biophysical properties of proteins associated with misfolding and aggregation. However, their detection and quantification in clinical samples and an understanding of the mecha ...

Expression proteomics study to determine metallodrug targets and optimal drug combinations

Paul Joseph Dyson, Kai Johnsson, David Hacker, Claire Samantha Allardyce

The emerging technique termed functional identification of target by expression proteomics (FITExP) has been shown to identify the key protein targets of anti-cancer drugs. Here, we use this approach to elucidate the proteins involved in the mechanism of a ...

Centriole Biogenesis: From Identifying the Characters to Understanding the Plot

Pierre Gönczy, Niccolo Banterle

The centriole is a beautiful microtubule-based organelle that is critical for the proper execution of many fundamental cellular processes, including polarity, motility, and division. Centriole biogenesis, the making of this miniature architectural wonder, ...

Proteoliposomes - a system to study membrane proteins under buffer gradients by cryo-EM

Henning Paul-Julius Stahlberg

Membrane proteins are vital to life and major therapeutic targets. Yet, understanding how they function is limited by a lack of structural information. In biological cells, membrane proteins reside in lipidic membranes and typically experience different bu ...

Enhancing Structure Prediction and Design of Soluble and Membrane Proteins with Explicit Solvent-Protein Interactions

Patrick Daniel Barth

Solvent molecules interact intimately with proteins and can profoundly regulate their structure and function. However, accurately and efficiently modeling protein solvation effects at the molecular level has been challenging. Here, we present a method that ...
