These include analyzing novel targets, understanding disease mechanisms, structure-based drug design, and discovering the mode of action of lead compounds. Nature 511, 616620 (2014). Lastly, the authors used machine learning approaches to build a model that would predict COVID-19 outcome as severe or less severe. Nat. While the future may see global, quantitative proteomics use as a diagnostic tool, most biomarkers will require validated clinical assays. Data from Phase 3 clinical trials is also critical for reverse translation, understanding not only what pathways and disease pathologies are impacted by the successful drug, but also which pathways and pathologies remain unchanged thus providing potential targets for future drug discovery. Chem. Despite Top Down proteomic methods promising to help resolve the isoform conundrum, and deciphering protein-isoforms at the purified protein level [Citation182], the community has yet to demonstrate the technologys utility in a robust manner, particularly at the level of sensitivity and throughput that are of general use for fast pathway analyses. Several pharmacologically relevant target classes such as multispan transmembrane receptors and ion channels are notoriously difficult to access with a lysate-based workflow run in discovery mode since they require the cellular context for binding competence. The dynamics of protein complexes also remains a technologically challenging arena. Bolden, J. E., Peart, M. J. Imagine if one could dissect a metastatic tumor and be able to analyze the T cell epitope repertoire directly for the development of a personalized cancer immunotherapeutic program, rather than rely on a combination of genomic analyzes and in silico prediction tools? 1.

ACS Chem. Nat. Rev. For some analyses that are routinely performed there is still some guess work involved, or at least incorporation of algorithms that make assumptions about the data that is being used as a database or to interpret downstream analyses. Implementation of this approach improves data accuracy and allows for similar proteomic depth to be achieved in half of the analysis time [Citation29]. As described above, isobaric label-based multiplexing approaches are challenged by ratio compression caused by multiple peptides being isolated simultaneously during fragmentation [Citation14]. Biosyst. Various studies have been performed to probe the complex architecture that is the cell, including single-cell variations, dynamic protein translocations, changing interaction networks and proteins that can localize to various sub-cellular compartments, allowing researchers to further unravel human disease biology [Citation195,Citation196].

Photoaffinity-labeling (PAL) allows the interrogation of compound-protein interactions in living cells since a typical PAL probe consists of three elements: the pharmacophore responsible for target binding, a functional group for installing an affinity handle and a photoreactive moiety (e.g., diazirine, benzophenone) that allows proximity-based covalent labeling of the interacting protein(s) upon cell irradiation. MRMAssayDB is a comprehensive resource for targeted assays with information on assays for over 50,000 proteins [Citation178]. This has changed with the current rise of chemical biology-inspired modalities and in particular those utilizing compound-induced recruitment of an effector protein to a (neo)substrate. 16, 89100 (2017).

Nat. In addition, for any given approach run in an unbiased fashion for de-novo target deconvolution, success is to some extent target-dependent, i.e., not every binding event leads to detectable thermal stabilization or conformational change under the selected set of experimental conditions. In addition, reduced sample complexity is often correlated with easier data analysis (no chemical tag modification to add to the search parameters, no deconvolution of data needed as is required with a multiplexing approach). Their analyses showed that single cell analyses could define a stable core proteome, a proteome subset in the MS-based proteomics data composed of the top 150 proteins with the lowest CVs of the proteins shared between at least 70% of the more than 420 single-cell measurements in their study, including drug perturbations analyses.

Low internal decision-making use. Sun, R. et al. Drug Discov. ACS Chem. Biol. 28, 413.e17 (2021). The coming years will define how applicable this approach is within a drug development or clinical setting, but the studies such as the one described here are an example of how this approach could relate to important disease models. The fact that chemoproteomics identifies physical interactions independent of functional relevance turns from being a disadvantage in the context of efficacy target identification into an advantage, as it provides the most comprehensive picture of both functional and silent compound-protein interactions that can be exploited using different modalities. Nat. In addition, such electrophilic probes can be used for protein level enrichment analyses and have been shown to provide overlapping but not identical information to isoTOP-ABPP-like approaches, e.g., shown for selectivity profiling for KRAS G12C inhibitors [Citation102]. Global subcellular characterization of protein degradation using quantitative proteomics. Biol. 5, 647654 (2009). As new cell biology arenas become more mainstream such as the implementation of synthetic biology, non-canonical amino acids as tools for spatial and temporal analysis of proteome dynamics as well as reagents for engineering new chemistries of functionalities into proteins will need to be analyzed in robust and sensitive manners.
