One example of this is the recent exploration of dark matter material in our genome, or the genome/proteome of an individual that does not confer to the traditional paradigm of proteins being produced due to canonical translation events. By extrapolating the MS/MS identification from one run and using it to detect/quantify a peptide in another mass spectrometric run with the same parameters file and chromatographic profile, one can increase the number of quantified species without having to trigger MS/MS in each run.

Chemoproteomics profiling of HDAC inhibitors reveals selective targeting of HDAC complexes. The collection of large scale proteomic, genomic, proteomic, and lipidomic datasets offers the opportunity to combine these data modalities and build functional networks important in the severity or progression of disease.

To obtain Syst. As a well-established, robust workflow with known characteristics, for the lysate-based pulldown approach to stay relevant developments will aim on the one side to decrease input material requirements to allow application to small, disease-relevant cell populations including primary cells and patient-derived material. These therapeutically relevant dark matter antigens are of interest for both cancer vaccine and T cell therapy approaches, where common, tumor specific antigens represent ideal targets. Chemical proteomics reveals ferrochelatase as a common off-target of kinase inhibitors. As mass spectrometric sensitivity and multiplexing capabilities increase it is possible that carrier proteomes will become obsolete, but until that time research should proceed with caution as they collect and interpret data from methods that rely on carrier proteomes to enable deep proteome quantification. Recently, a number of groups have begun to work toward building such repositories. And while multi-omic integration is still evolving, examples of disease-relevant studies are starting to emerge.

Examples where proteomics provided crucial data toward MoA elucidation include the discovery that the efficacy of lenalidomide in multiple myeloma is explained by CRBN-dependent degradation of transcription factors IKZF1 and 3 [Citation118]. Drug Discov. New and diverse findings of clinical relevance will emerge in the next decade, and these unknown unknowns in terms of how the proteome can be modulated beyond our current understanding will continue to shape the role of proteomics in drug discovery. Enhancements in sensitivity, integration of proteomics with other omics technologies, expansion and higher utility of chemoproteomic technologies & advances in biomarker discovery in addition to software and data analysis solutions are all evolving and merging to provide more intricate and informative data to help fuel the drug discovery and development pipeline. Nat. 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 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].
