The performance of LC-MS/MS and affinity-based array technologies were evaluated in a study of 173 human plasma samples [Citation158]. Using these principles, it is clear that early SCoPE MS data suffered from quantitative noise and inaccuracies (CV > 40%), but more recent data such as the iBASIL study (above) appears to be much higher quality. Larance, M. & Lamond, A. I. Multidimensional proteomics for cell biology. The functional landscape of the human phosphoproteome. Recent advances in high-throughput sample preparation and data acquisition including the BoxCar method [Citation121] have also allowed the rapid recording of compound-induced changes at the global proteome level [Citation122] or for a set of phosphorylation sites (P100) [Citation123] as signatures to derive compound MoA hypotheses either directly or via correlation to signatures of compounds with known MoA, akin to e.g. Parker, C. G. et al. This article is a landmark study that introduces activity-based protein profiling. With SCoPE-MS, quantitative chemical labels (e.g., TMTs) are utilized to provide an additive signal from a carrier proteome to boost qualitative and quantitative signals from an experimental sample [Citation15]. Cell surface thermal proteome profiling tracks perturbations and drug targets on the plasma membrane. Cell Rep. 8, 10371048 (2014). This effect can be alleviated by a gas phase purification technique called SPS-MS3 that utilizes dedicated sequencing and quantitative scans for each candidate peptide [Citation26,Citation27]. One such approach, the Covalent Inhibitor Target-site Identification (CITe-ID) workflow enabled the development of a PKN3 probe based on the observation that PKN3 is an off-target of the CDK inhibitor THZ1 [Citation101].

Lastly, the authors used machine learning approaches to build a model that would predict COVID-19 outcome as severe or less severe. the identification of phenyl hydroxylase as an off-target of the HDAC inhibitor panobinostat [Citation105]. In the proteomics community, we have traditionally navigated our bioanalytical analyses on the assumption that we understand the composition of the proteome. This is particularly true for non-canonical translation events that cannot be predicted from genome sequence alone. As most of the drugs are currently targeting proteins, proteomics has a dual value, both in the discovery of new molecules as therapeutic targets, but also as a methodology to perform high throughput drug profiling. Non-canonical amino acid labeling in proteomics and biotechnology, The nature of self for T cells-a systems-level perspective, Spliced peptides and cytokine-driven changes in the immunopeptidome of melanoma. Hughes, J. P., Rees, S., Kalindjian, S. B.

However, Ribo-seq results are more powerful when combined with proteomic analysis that detect the protein product of the translation event. This method was initially implemented within the native instrument code, but later adapted to utilize the flexible vendor method file format [Citation20]. Metab. Schlz, C. et al. 7, 13404 (2016). Chemical proteomic profiling of bromodomains enables the wide-spectrum evaluation of bromodomain inhibitors in living cells.
