As new cell biology arenas become more mainstream such as the implementation of synthetic biology, non-canonical amino acids as tools for spatial and temporal analysis of proteome dynamics as well as reagents for engineering new chemistries of functionalities into proteins will need to be analyzed in robust and sensitive manners. In addition to providing protein-level interactions, the latter approach has the potential to enable mapping of the protein regions affected by a binding event and in an ideal case the binding site itself via careful quantitation of individual proteolytic fragments using targeted MS or data-independent acquisition [Citation112,Citation113].

The promise of multi-omics workflows to decipher intricate cellular signaling mechanisms at a cellular level has held great promise, however it is only now that we see the true union of genomic sequencing technologies with proteomics, metabolomics and other cellular readouts as analytical tools become more sensitive, and software analysis enables integration of these data sets in a meaningful way. While the focus of biomarker discovery reported in the literature has been the identification of diagnostic tools, biomarkers play other critical roles in the clinical development of novel therapeutics. The recent boom of the proteomics field, or the analysis of the ever dynamic organismal proteome, has brought many advances with respect to the very nature of how the current drug discovery process is undertaken. Drug Discov. Gundry, J., Glenn, R., Alagesan, P. & Rajagopal, S. A practical guide to approaching biased agonism at G protein coupled receptors. Invest. Data from Phase 3 clinical trials is also critical for reverse translation, understanding not only what pathways and disease pathologies are impacted by the successful drug, but also which pathways and pathologies remain unchanged thus providing potential targets for future drug discovery. 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. These include issues related to the discovery sample set; including insufficient size, lack of appropriate controls, and changes in the patient population between discovery and validation experiments.

Another large scale protein sequencing project associated with the cancer cell line encyclopedia (CCLE) surveyed 375 cancer cell lines at an average depth of 8,500 proteins [Citation63]. LC-MS/MS was performed in the DIA and DDA modes using a Q Exactive HF instrument (Thermo) and affinity proteomics used the Olink PEA platform to measure the relative abundance of 736 protein analytes. 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. Soc. Monitoring drug target engagement in cells and tissues using the cellular thermal shift assay. In the near future, it is possible that a sufficiently sophisticated deep learning algorithm could consider an MS spectrum, retention time, and collisional cross section to predict a peptide sequence without performing a database search. 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. J. Anal. 12, 759770 (2021). 9, 232240 (2013). Nat. From a target perspective this means that essentially any small molecule-binding event to a protein of interest can be functionalized, even if the binding event itself is silent. While chemoproteomics has made crucial contributions to the identification of recruitment modules for, e.g., E3 ubiquitin ligase components like CRBN [Citation75], it is the large scale identification of ligands for targets of interest where it will most likely be most impactful. These include analyzing novel targets, understanding disease mechanisms, structure-based drug design, and discovering the mode of action of lead compounds.

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]. Biochemistry 46, 350358 (2007). First description of single cell proteomics with common laboratory cell line strains and the seminal paper that started the current excitement in single cell proteomics. Rather than transitioning from DIA based discovery experiments using Orbitrap instruments, to MRM validation experiments using triple quadrupole instruments, that requires additional equipment and expertise, validation could be done on the same Orbitrap instrument using PRM. With the emergence of machine learning algorithms and real-time searching, more de novo sequencing approaches [Citation200] might come of age and more on the fly database generators.
