Registered in England & Wales No. 11, O111 016717 (2012). but here we review the techniques available for global proteomic profiling, and the mass spectrometric approaches being utilized to achieve low level analyses here can be generalized into two approaches; a label-free approach, and a chemically tagged labeling technique, where reagents such as TMTs are employed for multiplexing samples and collectively amplifying signals from pooled analytes. Cell 161, 16681680 (2015). Nature 509, 582587 (2014). For example, when determining if a protein is a TAA a common practice is to use data within The Cancer Genome Atlas (TCGA) which has both tumor and normal tissue expression data. Qin, P. et al. 2, 185195 (2016). Plasma proteome profiling to assess human health and disease. 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. Therefore, TPD drug discovery projects rely heavily on proteomics for target identification and compound characterization and optimization.

With the emergence of macrocycles [Citation187], aptamers [Citation188] and other new probe based technologies, additional new areas of the proteome and their interactions will be revealed as these tools become part of the proteomic toolbox. As the sensitivity of mass spectrometers continues to improve, intelligent data acquisition (IDA) enabled by real-time analysis of MS data has enabled more sophisticated data collection methods as well as increased the efficiency and depth of proteomic analyses. However, current iterations of RTS are still limited in the size of the database that can be interrogated within the limited time available between peptide sequencing scans (20ms).

The Multiplexed Proteome Dynamics Profiling (mPDP) workflow further allows additional differentiation of direct compound-induced protein degradation from downstream effects and has been used, e.g., to compare the effects of the heterobifunctional JQ1-VHL degrader vs. the bromodomain inhibitor JQ1 alone [Citation120]. 14, 120135 (2015).

At present, proteomics is used pre-clinically for target identification and characterization, drug candidate selection and characterization, and clinically for biomarker discovery and development. 11, 25412550 (2016). 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. 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. Biotechnol. Urine [Citation159] and stool [Citation160] in particular have the additional advantage of being noninvasive, simple to collect, store and transport. Klaeger, S. et al. Taunton, J., Hassig, C. A. Parker, C. G. et al. 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 such approach, the Covalent Inhibitor Target-site Identification (CITe-ID) workflow enabled the development of a PKN3 probe based on the observation that PKN3 is an off-target of the CDK inhibitor THZ1 [Citation101]. These data demonstrate that the true impact of a carrier proteome and its utility in analyzing low level and single cell samples is still being understood. This is followed by 3) separation of compound-interacting proteins from the rest of the proteome by a variety of means including affinity enrichment or detection of changes in protein stability upon compound binding. Various mass spectrometric techniques have been employed to analyze increasingly less abundant proteins from a complex proteome. https://doi.org/10.1038/s41573-022-00409-3, DOI: https://doi.org/10.1038/s41573-022-00409-3.

Using these principles, it is clear that early SCoPE MS data suffered from quantitative noise and inaccuracies (CV > 40%), but more recent data such as the iBASIL study (above) appears to be much higher quality. 24, 787800 (2017). Nature 529, 263264 (2016). Jafari, R. et al. 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. Chem. 18, 83 (2017). In the pharmaceutical industry, proteomics has long been utilized as a drug-discovery tool to help understand changes in protein profiles for disease states or protein expression in relation to genomic studies for target discovery or identification [ 1 ]. Hahm, H. S. et al. Article Trends Biochem. Cell Proteom. A commonly used strategy to increase proteome coverage is to use pre-fractionation. 6, ra25 (2013). 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. By coupling these instrument setting advancements with nanoPOTS, iBASIL enabled identification of 2500 proteins and precise quantification of 1500 proteins in the analysis of 104 FACS-isolated single cells [Citation16]. 15, 533550 (2016). The observation that the number of biomarker candidates identified in the literature is perhaps a quarter of human proteins, suggests that the candidate discovery process is often not rigorous enough [Citation133]. This method was initially implemented within the native instrument code, but later adapted to utilize the flexible vendor method file format [Citation20]. 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]. Peer reviewers on this manuscript have no relevant financial or other relationships to disclose. J. Med. Nature 486, 554558 (2012). Proteins do many different things in the body, but one of the most common roles is to use and create metabolites such as vitamins and sugars. Metabolic labeling of proteins with non-canonical amino acids allows incorporation of biorthogonal chemical groups into proteins by taking advantage of both endogenous and heterologous protein synthesis machinery.
