alpha-Synuclein O-GlcNAcylation alters aggregation and toxicity, revealing certain residues as potential inhibitors of Parkinson's disease

Hilal Lashuel, Anne-Laure Mahul Mellier

A compelling link is emerging between the posttranslational modification O-GlcNAc and protein aggregation. A prime example is alpha-synuclein, which forms toxic aggregates that are associated with neurodegeneration in Parkinson's and related diseases. alph ...

Production of active glycosylation-deficient gamma-secretase complex for crystallization studies

Florian Maria Wurm, David Hacker, Patrick Fraering, Mitko Dimitrov, Hermeto Gerber, Virginie Sandra Braman

Alzheimer's disease (AD)-associated gamma-secretase is a ubiquitously expressed multi-subunit protease complex embedded in the lipid bilayer of cellular compartments including endosomes and the plasma membrane. Although gamma-secretase is of crucial intere ...

N-linked sugar-regulated protein folding and quality control in the ER

Maurizio Molinari

Asparagine-linked glycans (N-glycans) are displayed on the majority of proteins synthesized in the endoplasmic reticulum (ER). Removal of the outermost glucose residue recruits the lectin chaperone malectin possibly involved in a first triage of defective ...

Flagging and docking: dual roles for N-glycans in protein quality control and cellular proteostasis

Maurizio Molinari

Nascent polypeptides entering the endoplasmic reticulum (ER) are covalently modified with pre-assembled oligosaccharides. The terminal glucose and mannose residues are immediately removed after transfer of the oligosaccharide onto newly synthesized polypep ...

Glycosylation pathways as drug targets for cancer: glycosidase inhibitors

Sandrine Gerber

The combined and ordered sequential action of glycosidases and glycosyltransferases in mammalian cell compartments leads to the addition of defined glycans to proteins and lipids. Altered glycosylation patterns, neoexpression, underexpression or overexpres ...
