Posttranslational modifications (PTMs) are covalent processing events that change the properties of a protein by addition of a modifying group to one or more of its amino acids. Due to its prominent role in cellular signaling, protein phosphorylation is one of the most studied PTMs.
Mass spectrometry-based phosphoproteomics now routinely measures tens of thousands of phosphorylation sites on a proteome-wide scale. Increasing the throughput and sensitivity of phosphoproteomics approaches is highly desirable to disentangle their functional relevance.
