Weerapana, E. et al. Science 346, 1255784 (2014). Nat. described an approach that links each amino acid to a cationic carrier of seven arginine amino acids and passes this new polypeptide through an aerolysine nanopore for sequencing [Citation38]. For many years, technologies such as microscopy have allowed dissection of biological events at a cellular level, however it is only in recent years that genomic sequencing techniques have also advanced to routinely allow analysis of cell-specific mediated events rather than an averaged overview of cellular cluster or tissue-level activities.

Unlike our genomic counterpart technologies, proteomics is not blessed with tools such as the polymerase chain reaction (PCR) to amplify low level biomaterial; instead, researchers must rely on advances in technologies to detect low level protein and peptide signals. 16, 424440 (2017). Inhibition of BET recruitment to chromatin as an effective treatment for MLL-fusion leukaemia. In parallel to label-free detection methods for low level proteomic analysis, a method called Single Cell ProtEomics by Mass Spectrometry (SCoPE-MS) has gained significant momentum.

Proteomics in drug development: the dawn of a new era? In addition, an estimate of the level of validation needed to support the biomarker is indicated, ranging from low to high where low refers to biomarkers used for internal decision making, medium refers to biomarkers that are submitted to regulatory agencies to support the filing, and high refers to biomarkers that impact diagnostics and companion diagnostics. The authors declare no competing interests. Reducing sample preparation time and the number of adherent surfaces that come into contact with it, can all contribute to more sensitive analyses. The SysteMHC Atlas project. Nat. Cell Proteom. Chem. capturing the experimental meta data associated with a mass spectrometry experiment is vital to re-analysis. 10, M111 013284 (2011). Historically, the focus has been on identification of functionally relevant interactions such as efficacy target identification where complementary, in particular genetic approaches were required to prioritize physical interactors identified by chemoproteomics hits by functional relevance (and vice versa since genetic screening hits often include additional components of the target biology network).

N-terminomic proteomic profiling (TAILS) was used to identify novel substrates of HtrA1, a serine hydrolase associated with increased risk of age-related macular degeneration (AMD) in preclinical models. Lab. 9, 36883700 (2010). In addition, NMR-metabolomics and O-link data was performed on participants who were recruited for a long term study spanning > a decade at this point. Biomarkers submitted to regulatory agencies may need to be formally reviewed or qualified. There are two typical paths for biomarker qualification either through submission of biomarker data during drug approval, or independently via the FDA biomarker qualification program [Citation139]. Cell Chem. By also incorporating the Match Between Runs (MBR) algorithm [Citation8], > 3000 proteins were consistently identified from as few as 10 cells. More specific approaches may be applicable in certain cases, such as the use of TAILS to identify novel protease substrates as discussed previously [Citation145]. Vinken, M. The adverse outcome pathway concept: a pragmatic tool in toxicology. Impact of phosphorylation on thermal stability of proteins. Cell 149, 307321 (2012). However, despite extensive effort, and decades of research, there have been very few success stories. Reddy, A. S. & Zhang, S. Polypharmacology: drug discovery for the future. 27, 34513453 (2019).

Just recently, stealth-mode startups Nautilus Biotechnology and Quantum-Si have emerged with the stated goals of developing commercial next generation proteomics platforms. This is due to the low insertion efficiency of available photo-reactive moieties as well as the fact that the carbene radical-based, random insertion process tends to give rise to a mixture of molecular modification products even for a single binding pocket and a given peptide sequence. The same advances in throughput, proteome coverage, and quantitation that are improving biomarker candidate discovery will accelerate these applications as well. 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). Applications of proteomics in drug discovery and development, https://doi.org/10.1080/14789450.2021.1962300, Medicine, Dentistry, Nursing & Allied Health. While the chemoproteomics workflows described so far are most often used for non-covalent screening hits, the resurgence of covalent drug discovery, including the use of electrophile libraries in cell-based screens, has led in parallel to an increased interest in covalent chemoproteomics or activity-based protein profiling (ABPP) approaches. 16, e9111 (2020). Klaeger, S. et al. The latter will lead to the biological effect, which can range from target degradation in a ubiquitination-dependent manner by the proteasome system [Citation125] or via autophagy [Citation126] to modulation of phosphorylation-dependent events by recruitment of kinases [Citation127] or phosphatases [Citation128]. Drug Discov. Anal. The Biomarkers, EndpointS and other Tools (BEST) resources developed by the FDA-NIH Biomarker Working Group is a valuable resource which classifies and defines biomarker categories and also describes biomarker validation and qualification [Citation138]. A draft map of the human proteome. Krastel, P. et al. As mass spectrometry based proteomic technologies continue toward enabling single cell sensitivity, the era of next generation peptide and protein sequencing is imminent. CITe-ID also provides direct evidence of the compound adduct instead of relying on indirect, competition-based information. Monitoring drug target engagement in cells and tissues using the cellular thermal shift assay. 7, 12581 (2016). Nat. As a result, these workflows allow not only the identification of protein interactors for a compound of interest, but more specifically the mapping of modified sites and thus ligandable pockets. Nature 468, 10671073 (2010). 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. Sci. Saei, A. Cell 131, 11901203 (2007). This begins with how a sample is collected in the laboratory or the clinic, how it is then prepared, derivatized and separated, to how it is analyzed both biophysically as well as via data analytics.
