New and diverse findings of clinical relevance will emerge in the next decade, and these unknown unknowns in terms of how the proteome can be modulated beyond our current understanding will continue to shape the role of proteomics in drug discovery. Like many scientific fields, proteomics is currently undergoing a machine learning revolution. Renaud, J. P. et al. Am. Nat. Bioorg. J. Proteome Res. In general, chemoproteomics workflows share four general steps, each of which will be the focus of technology development efforts in the coming years to improve comprehensiveness and disease-relevance of generated information as well as throughput and scalability of the workflow (see Figure 3). To facilitate the process, several biotechnologies, including genomics, proteomics,. The challenges associated with proteomics-based biomarker discovery, referred to as the discovery to validation gap, have been reviewed previously [Citation133136] and a number of factors have been identified that contribute to the failure to validate discovery findings. Am. Cell Chem. Xtalks, powered by . The probability of a successful launch for drug candidates entering Phase 1 clinical trials is approximately 10% [Citation70]. Sci. Illing, P.

Therefore, it will be exciting to watch how this scientific area will evolve in terms of methodology, instrumentation and software, as well as data integration: it will no doubt look very different in the future than what we consider feasible right now. Science 287, 20072010 (2000). Br. Today 14, 10211029 (2009). Cell 163, 14841499 (2015). Neurosci. Natl Acad. Proc.

Proteomics has evolved to address increasingly complex biological questions, unravel new intracellular signaling pathways leading to new therapeutic targets and has helped decipher key pathway modulators and biomarkers [Citation1]. Lab. 19, 414426 (2020). For example, Overmyer et al. Uetrecht, J. Idiosyncratic drug reactions: current understanding. Nat. Finally, while it is tempting to do biomarker discovery in plasma, given the complexity of the plasma proteome it may make more sense to analyze other matrices closer to the sites of action such as CSF, stool, urine, synovial fluid, tears, aqueous humor, saliva, skin blister fluid, tissue, etc. Such databases would prove invaluable for late-stage therapeutic development where protein expression can often determine the risk of off-target toxicity. The third step is an iterative process of biomarker assay development and analytical validation, and biomarker qualification. Proc. 25, 137147 (2020). Mass-spectrometry-based draft of the human proteome. Science 358, eaan4368 (2017). Brief.

Cold Spring Harb. Nat. Science 272, 408411 (1996). In addition to affinity enrichment-based approaches, a number of proteomics approaches have been introduced that use compound-induced changes in thermodynamic stability or conformational changes in the target protein to identify and characterize compound-target interactions. 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. Chem. Precision diagnostics: moving towards protein biomarker signatures of clinical utility in cancer. Again, competition-based workflows can help with both specificity as well as prioritization of functionally relevant interactors [Citation80]. ACS Chem.

Capturing the spatial proteome that is, the localizations of proteins and their dynamics at the subcellular level is therefore essential for a complete understanding of cell biology. The promise of multi-omics workflows to decipher intricate cellular signaling mechanisms at a cellular level has held great promise, however it is only now that we see the true union of genomic sequencing technologies with proteomics, metabolomics and other cellular readouts as analytical tools become more sensitive, and software analysis enables integration of these data sets in a meaningful way.

Such a "random" approach entails testing numerous compounds and developing countless highthroughput screening assays. This includes more sensitive sample preparation on more diverse cellular types and biological fluids, data collection, and analysis. At the same time, chemoproteomics experiments typically yield additional binding off-targets which can be functionally relevant in a different biological context such as explain potential toxicity mechanisms but also provide opportunities for drug repurposing (reviewed in PMID: 33,404,270).
