Front Cover: Control of lipid metabolism by the dynamic and nutrient‐dependent post‐translational modification <i>O</i> ‐GlcNAcylation

Post-translational modifications act as rheostats of protein activity. Many them reflect environmental variations and allow the cell to give an adapted response these changes. In this cover article #Ref, Céline Schulz collaborators provide in-depth overview still underrated role nutrient-dependent post-translational modification O-GlcNAcylation in regulation metabolism lipids, a very heterogenous family with diverse functions.
