Lipid bilayer-bound conformation of an integral membrane beta barrel protein by multidimensional MAS NMR

David Lyndon Emsley

The human voltage dependent anion channel 1 (VDAC) is a 32 kDa β-barrel integral membrane protein that controls the transport of ions across the outer mitochondrial membrane. Despite the determination of VDAC solution and diffraction structures, a structur ...

The FDA-approved natural product dihydroergocristine reduces the production of the Alzheimer's disease amyloid-beta peptides

Patrick Fraering, Jianhua Liu, Jing Yu

Known gamma-secretase inhibitors or modulators display an undesirable pharmacokinetic profile and toxicity and have therefore not been successful in clinical trials for Alzheimer's disease (AD). So far, no compounds from natural products have been identifi ...

The adipocyte differentiation protein APMAP is an endogenous suppressor of Aβ production in the brain

Bernard Schneider, Patrick Fraering, Mitko Dimitrov, Sébastien Mosser, Justine Pascual, Alexandre Matz

The deposition of amyloid-beta (Aβ) aggregates in the brain is a major pathological hallmark of Alzheimer's disease (AD). Aβ is generated from the cleavage of C-terminal fragments of the amyloid precursor protein (APP-CTFs) by γ-secretase, an intramembrane ...

Identification of new Presenilin-1 phosphosites: implication for gamma-secretase activity and A beta production

Romain Hamelin, Patrick Fraering, Marc Moniatte, Mitko Dimitrov, Sébastien Mosser, Alexandre Matz, Blanka Halamoda

An important pathological hallmark of Alzheimer's disease (AD) is the deposition of amyloid-beta (A) peptides in the brain parenchyma, leading to neuronal death and impaired learning and memory. The protease -secretase is responsible for the intramembrane ...

Perturbations of the Straight Transmembrane alpha-Helical Structure of the Amyloid Precursor Protein Affect Its Processing by gamma-Secretase

Matteo Dal Peraro, Patrick Fraering, Mitko Dimitrov, Thomas Lemmin

Background: Amyloid- neurotoxicity depends on the specificity of the proteolytic cleavage of the amyloid precursor protein (APP) transmembrane domain. Results: The APP transmembrane -helix is straight in a biological membrane bilayer. Conclusion: The flexi ...

In cases where ultra-flat cryo-preparations of well-ordered two-dimensional (2D) crystals are available, electron crystallography is a powerful method for the determination of the high-resolution structures of membrane and soluble proteins. However, crysta ...

Cryo-electron microscopy of membrane proteins

Henning Paul-Julius Stahlberg

Electron crystallography is used to study membrane proteins in the form of planar, two-dimensional (2D) crystals, or other crystalline arrays such as tubular crystals. This method has been used to determine the atomic resolution structures of bacteriorhodo ...

2D crystallography has proven to be an excellent technique to determine the 3D structure of membrane proteins. Compared to 3D crystallography, it has the advantage of visualizing the protein in an environment closer to the native one. However, producing go ...
