A third of the human genome encodes N-glycosylated proteins. These are co-translationally translocated into the lumen/membrane of the endoplasmic reticulum (ER) where they fold and assemble before they are transported to their final destination. Here, we show that calnexin, a major ER chaperone involved in glycoprotein folding is palmitoylated and that this(More)
S-palmitoylation is post-translational modification, which consists in the addition of a C16 acyl chain to cytosolic cysteines and which is unique amongst lipid modifications in that it is reversible. It can thus, like phosphorylation or ubiquitination, act as a switch. While palmitoylation of soluble proteins allows them to interact with membranes, the(More)
S-Palmitoylation, the only reversible post-translational lipid modification, confers unique biochemical and functional properties to proteins. Although it has long been known that viral proteins are palmitoylated, recent studies reveal that this modification plays a critical role for pathogens of all kinds and at multiple steps of their life cycle. The(More)
S-palmitoylation involves the attachment of a 16-carbon long fatty acid chain to the cysteine residues of proteins. The process is enzymatic and dynamic with DHHC enzymes mediating palmitoylation and acyl-protein thioesterases reverting the reaction. Proteins that undergo this modification span almost all cellular functions. While the increase in(More)
Genes of the p53 family are known to be critical regulators of the cell cycle. They have already been established as possible biomarkers. Elaborate regulation mechanisms result in numerous cDNA and protein isoforms being expressed from each gene of the p53 family. Their similarity caused an often misleading nomenclature in non-vertebrate species. The aim of(More)
