Drug Discov. Inhibition of BET recruitment to chromatin as an effective treatment for MLL-fusion leukaemia. In addition, while mass spectrometers currently remain the primary analytical approach for the characterization of peptide and proteins, additional technologies characterize proteins are emerging as single molecule sequencing techniques are emerging, and antibody-based readouts are becoming more sophisticated as they merge with DNA-barcoding and other infinitely more sensitive technologies. This paper is a landmark study introducing the CETSA. Mol. 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. Of the 28 quantifiable proteins, 10 showed significant differences between diagnostic groups and 4 candidates demonstrated a significant longitudinal change consistent with their utility as potential monitoring biomarkers. Biol. Ruoho, A. E., Kiefer, H., Roeder, P. E. & Singer, S. J. This is primarily due to the emergence of targeted protein degradation (TPD) as a novel modality where pharmacological intervention results in modulation of target protein levels by recruitment of a target of interest to a suitable E3 ligase component such as CRBN or VHL to induce proteasome-dependent degradation. If the protein products of these translation events are rapidly turned over, it stands to reason that they would be more readily presented on the cell surface. Toxicol. Lab head and builder of state-of-the-art LC-MS/MS labs most recently building a lab end-to-end from the ground up complete with bench, analytical, and compational proteomics capabilities paired . 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. This is particularly important as new therapeutic modalities, such as cellular therapies, aim to target proteins upregulated in tumor tissue (tumor associated antigens, TAA) or the mutated cancer proteins. This is supported by the fact that the authors found 240 HLA-I associated peptides from these distinct ORFs. Uhlen, M. et al.

Proteomics technologies present a means of providing evidence early in a drug discovery program that a target is not worthwhile, yielding significant cost savings to pharma companies whilst also ultimately helping patients and the healthcare systems . 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). 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.

Overview of common steps of the various chemoproteomics workflows described in the text with specific areas of active optimization and method development. Phosphoproteomics reveals that Parkinsons disease kinase LRRK2 regulates a subset of Rab GTPases. As an alternative to the purely competitive, peptide-based approaches described so far, covalent chemoproteomics workflows can also be based on specific electrophilic probes derived from the original compound of interest, akin to the PAL probes discussed previously. 14, 294 (2015). While it is a common practice to deposit raw MS data such that it can be accessed and re-analyzed, the vast diversity of proteomics data collection (e.g., DDA, DIA, targeted) and data analysis (e.g., MaxQuant, Proteome Discoverer, PEAKS, in-house approaches) techniques can make it difficult to quickly determine if a protein was detected and if so how much was there. Med. Methods 12, 10551057 (2015).

The challenges associated with clinical validation are likely enough to discourage replication unless a clear, cost effective use case can be made. For example, recent improvements in MS instrumentation led to the number of peptides sequenced per outpacing available candidates for sequencing leading to lost instrument time [Citation21]. With SCoPE-MS, quantitative chemical labels (e.g., TMTs) are utilized to provide an additive signal from a carrier proteome to boost qualitative and quantitative signals from an experimental sample [Citation15]. 83, 341377 (2014).
