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 approaches ultimately produce data of similar or better quality without the upfront costs of performing a DIA experiment and facilitate the utilization of DIA for a wide range of applications. Genomics concerns itself with identifying what genes are associated with a specific disease. Phosphoproteomic mass spectrometry profiling links Src family kinases to escape from HER2 tyrosine kinase inhibition. Various studies have been performed to probe the complex architecture that is the cell, including single-cell variations, dynamic protein translocations, changing interaction networks and proteins that can localize to various sub-cellular compartments, allowing researchers to further unravel human disease biology [Citation195,Citation196]. Garber, K. Kinase inhibitors overachieve in CLL. 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].

F. Mapping the protein interaction landscape for fully functionalized small-molecule probes in human cells. Nat. Biochem. 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. 9, 36883700 (2010). 14, 14001410 (2015). personalized cancer vaccines or engineered T cell therapies) has traditionally been limited to tumor associated antigens and shared cancer mutations. 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. Chem. Google Scholar. 9, 15401553 (2010). Perhaps even more significant, in the large majority of cases, discovery experiments are simply not followed up and validation is not even attempted. At present, proteomics is used pre-clinically for target identification and characterization, drug candidate selection and characterization, and clinically for biomarker discovery and development. Rev. Their analyses showed that single cell analyses could define a stable core proteome, a proteome subset in the MS-based proteomics data composed of the top 150 proteins with the lowest CVs of the proteins shared between at least 70% of the more than 420 single-cell measurements in their study, including drug perturbations analyses.

Although there have been over 100 published studies to identify potential diagnostic and prognostic biomarkers for Alzheimers Disease (AD) in cerebrospinal fluid (CSF) [Citation148], a key drug development need is for monitoring biomarkers. Martinez et al. Biol. Chem. Further development of screening libraries with increasingly sensitive readouts will continue to allow the biotechnology field to probe hard to access parts of the proteome and decipher important cellular interactions. Proteomics plays an important role in the discovery, validation and implementation of these biomarkers, which require distinct, fit-for-purpose approaches. In the coming years, as RTS algorithms become more efficient it will be possible to search databases that consider multiple post-translational modifications or nonspecific cleavages events. Nature 478, 529533 (2011). J. Biol. It comprises the design of drug, co-factor, substrate or inhibitor analogues that can be immobilized on a suitable medium to trap specic proteins or subgroups of interest.
