Proteins are effectors of most physiological functions in cells and they play a key role in the extracellular medium. Protein function is finely tuned at multiple levels including synthesis and degradation, intracellular localization and posttranslational modifications. The posttranslational modification of proteins is a key mechanism for the regulation of their biological activity. Various biological mediators, including lipids and reactive oxygen and nitrogen species, and also some drugs and toxins, can modify proteins posttranslationally. We are interested in the study of the importance of these processes in molecular pathophysiology and in the mechanisms of drug action. Our work includes several aspects: the structural and functional characterization of novel types of posttranslational modifications, the identification of novel protein targets for modification and the study of the pathophysiological consequences of these phenomena, mainly in the context of inflammatory and oncogenic processes.
