Metabolic enzymes enjoying new partnerships as RNA-binding proteins. A proteome-wide, quantitative survey of in vivo ubiquitylation sites reveals widespread regulatory roles. A key advantage common to all non-affinity enrichment-based approaches is that they do not require the time- and resource intensive generation and validation of an affinity tool compound and thus are ideal for higher throughput selectivity profiling. Klaeger, S. et al. The in silico approach, an important part of rational design of protein kinase inhibitors, is founded on vast information about 3D structures of these enzymes. 7, 12581 (2016). Building upon the MassIVE Knowledge Base [Citation65], MassIVE.quant includes experimental design information commonly lacking in public data repositories. USA 106, 2198421989 (2009). 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). Soc. While large, standardized studies offer the best opportunity to collect data that can be directly compared, there is currently an effort to make the numerous, bespoke quantitative proteomic analyses more amenable to re-analysis from non-experts. Cell Rep. 8, 10371048 (2014). Targeting KRAS mutant cancers with a covalent G12C-specific inhibitor. Fragment-based covalent ligand screening enables rapid discovery of inhibitors for the RBR E3 ubiquitin ligase HOIP. The importance of the throughput vs depth will vary depending on the specific application. Multiplexed proteome dynamics profiling reveals mechanisms controlling protein homeostasis. Such a "random" approach entails testing numerous compounds and developing countless highthroughput screening assays. Biological matrices and clinical samples including biomarkers. Cancer 17, 199204 (2017). The majority of workhorse mass spectrometric instrumentation currently claim an average limit of detection (LOD) of approximately 10 amol or 6 million 50-kDa protein molecules, which is orders of magnitude higher than where the field was just a decade ago, but still correlates with challenges associated with analyzing very low level biological materials. Int. 16, 531543 (2017). Chemoproteomics. Rev. Curr. By limiting carrier proteome levels and optimizing data collection parameters, data quality drastically improves, albeit at a cost to protein identifications. J. Proteome Res. Biological matrices where the dramatic range of protein concentrations poses analytical challenges are whole blood or serum, where antibodies may be present at concentrations as high as 1 mg/nL but immunomodulatory proteins such as cytokines or chemokines, popular targets for biological exploration or biomarkers of disease etiology are often present at a mere ng/mL concentration [Citation12]. There is a good reason for this as one needs a contained search environment to mitigate false negative and positive results. Nat Rev Drug Discov 21, 637654 (2022). Thermal proteome profiling monitors ligand interactions with cellular membrane proteins. Rev. Nat. USA 97, 82968301 (2000). Efficient proximity labeling in living cells and organisms with TurboID.

And imagine if one could rapidly analyze all of the proteoforms from just tens of cells from a xenograft model, or a few microliters of biofluid in a high throughput manner? in their comparison of single cell proteomics to scRNASeq [Citation5], again highlighting the importance of developing this field. Cell 180, 605632 (2020). Advancing targeted protein degradation for cancer therapy. Proteomics plays an important role in the discovery, validation and implementation of these biomarkers, which require distinct, fit-for-purpose approaches. Pathway analysis tools often concentrate on one type of data set at a time, rather than how to extrapolate these data in concert. Biol. More specific approaches may be applicable in certain cases, such as the use of TAILS to identify novel protease substrates as discussed previously [Citation145]. However, despite the availability of these tools, and the advantages of using targeted MS to validate promising biomarker candidates identified using MS based discovery experiments, a recent survey of the literature revealed that a large majority of discovery efforts lack validation, and those that are validated utilize immunoassays and not MS [Citation179]. Identification of KasA as the cellular target of an anti-tubercular scaffold. The proteomics database information that is available shows that it can be used for basic research, drug discovery, or decision making in the clinic. Whitby, L. R., Obach, R. S., Simon, G.

As mass spectrometry based proteomic technologies continue toward enabling single cell sensitivity, the era of next generation peptide and protein sequencing is imminent. Biol. Since the interrogated target space for each compound subjected to chemoproteomics is the full cellular proteome, databases of chemoproteomics data and their proactive expansion in screening mode will increasingly enable the identification of chemical starting points for these modalities. TMTpro reagents: a set of isobaric labeling mass tags enables simultaneous proteome-wide measurements across 16 samples. The basic premise of screening is that biological assays are reproducible, reliable, and robust and biologically relevant. Nahnsen, S., Bielow, C., Reinert, K. & Kohlbacher, O. Dou et al. Nat. Proc. Selective inhibition of BET bromodomains. Rev. Preprint at bioRxiv https://doi.org/10.1101/796391 (2019). After cell lysis, labeled proteins are enriched typically using a biotin-based system with the biotin introduced post-lysis using e.g. Chem. CAS Our aim is to deliver innovative tools that make drug development more efficient, more cost-effective, and more successful. While these workflows are used so far predominantly for cysteine-targeting compounds, they can per se be applied to any reactive amino acids for which pan-reactive probes are available. The mechanism of photoaffinity labeling. Cell Proteom. Bioorg. 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). 18, 14011412 (2011).

Zhao, Q. et al. Annu. We thank Allison Bruce for her help with the graphics and Orit Rosenblatt-Rosen and Mark McCarthy for insightful review. Proteomics will likely remain a key technology in the coming decade, but will have to evolve with respect to type and granularity of data, cost and throughput of data generation as well as integration with other technologies to fulfill its promise in drug discovery. A proof-of-principle study by Hacker and colleagues recently demonstrated that an optimized data analysis workflow enables the use of 54 different probes covering 9 amino acid and N-terminal modifications in parallel for a direct comparison of probe selectivity and extension more comprehensive monitoring or reactive sites in a proteome [Citation100].

Nannocystin a: an elongation factor 1 inhibitor from myxobacteria with differential anti-cancer properties. Cancer Cell 35, 414427.e416 (2019). 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. One example of this is the recent exploration of dark matter material in our genome, or the genome/proteome of an individual that does not confer to the traditional paradigm of proteins being produced due to canonical translation events. Pharmacol. Nat. Schirle, M., Bantscheff, M. & Kuster, B. Commun. Science 346, 1258096 (2014). Nat. Taken together, since translational and post-translational events are primary readouts for the cells biological functionality, we expect that proteomics will remain a key technology in the pharmaceutical and biotechnological arena in the coming decade.
