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. Becher, I. et al. Garber, K. Kinase inhibitors overachieve in CLL. Nat. While these are becoming increasingly available, including for lysine [Citation97], methionine [Citation98] and tyrosine [Citation99], the identification of novel probes that are more robust and allow access to additional amino acids remains of high importance. Savitski, M. M. et al. 15, 32333242 (2016). In order to increase specificity and allow prioritization of hits by likelihood of functional relevance, the experiments are typically performed in a competitive mode using preincubation of lysate with free parent compound in dose response or using analogs covering a range of cellular activity. Biotechnol. 24, 2737 (2015). This approach has proven to be most successful for soluble proteins that retain binding competence under generic cell lysis conditions such as the E3 ligase substrate receptor CRBN as the target of thalidomide [Citation75] or Annexin A2 as a target of bleomycin in bleomycin-induced pulmonary fibrosis (PMID: 29,172,997). Broad-spectrum kinase profiling in live cells with lysine-targeted sulfonyl fluoride probes. This step is critical; virtually any differential expression experiment will discover proteins that are up or down regulated between but few if any are actually potential clinical biomarkers. Analysis of dermatologic events in vemurafenib-treated patients with melanoma. Nat. More specific approaches may be applicable in certain cases, such as the use of TAILS to identify novel protease substrates as discussed previously [Citation145]. 6, a020768 (2014). Opin. Thompson, A. et al. Nat. Biol. 18, 35803585 (2019). For multiplexed samples that utilize TMT, the TMT reporter ions are known to potentially suffer from ratio compression [Citation14] which can lead to false negative quantitative results. Chemoproteomic profiling reveals that cathepsin D off-target activity drives ocular toxicity of beta-secretase inhibitors. Has the potential to significantly improve sensitivity of proteomics experiments. Biotechnol. 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. Nat. 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). Rev. Rep. 10, 5324 (2020). PromarkerD, a biomarker for predicting diabetic kidney disease based on multiplex immunoaffinity MS measurement of three plasma proteins (CDL5, APOA4, and IBP3) with three clinical variables (age, HDL-cholesterol, and eGFR) has been submitted to the FDA for approval, and was discovered using proteomics technology [Citation132]. Xtalks, powered by . Metab. 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. Qin, P. et al. Science 348, 13761381 (2015). Methods 16, 843852 (2019). While this complicates target deconvolution, it can allow on the other hand the observation of broader aspects of the compound MoA and effects on downstream processes.

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. Biotechnol. 16, 12161227 (2017). Loh, K. H. et al. 5, 647654 (2009). Although a general consensus regarding the optimal approach to quantitative proteomics for biomarker candidate discovery has not yet emerged, the field is rapidly advancing and the future looks very promising. In addition, these approaches offer an experimental framework to demonstrate target engagement in cells, model organisms and ultimately the patient in this case often using a more targeted detection and quantitation of the protein of interest to increase sensitivity and throughput. 1, 15006 (2016).

Earlier, we noted the now general observation that transcriptome does not always correlate with translated products, and this was also observed by Brunner et al. Dalton, S. E. et al. 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). Multiplexing technologies have increased the number of proteomes that can be analyzed in one experiment and have dramatically improved our ability to assay various genotypes, treatments, or time points in one discovery proteomics experiment. This paper reveals Rab proteins as the long-sought substrate of LRRK2. Angew.

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. Apart from improved data analysis strategies, experimental workflows have been introduced to aid with this process, e.g., the SIM-PAL workflow which uses introduction of unique isotopic patterns to identify probe-labeled peptides in digested enriched samples [Citation87]. Nature 369, 756758 (1994). Google Scholar. Peer reviewers on this manuscript have no relevant financial or other relationships to disclose.
