Proteomics strategies to study post-translational regulatory mechanisms in cell biology and disease

Cells respond to environmental cues, such as external signal or stresses, by dynamically remodeling their proteome. A great part of the proteome-level regulation within a cell happens post-translationally. Post-translational regulation can involve chemical modifications in the protein, but also subcellular relocation, secretion or targeted degradation. Mass spectrometry-based proteomics offers an exceptional platform to explore from a systems-level perspective all these dynamic mechanisms. In this talk, I will present how using MS-based proteomics we can study cell response and adaptation to stress from a post-translational perspective, either by studying the spatio-temporal dynamics within the cells or their modification status.
