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]. 6, e004453 (2017). Chemoproteomics profiling of HDAC inhibitors reveals selective targeting of HDAC complexes. Chem. In addition to successful target deconvolution for challenging transmembrane target families of interest such as solute carriers (e.g., SLC39A7/ZIP7 [Citation81], SLC25A20 [Citation82]), the introduced covalent bond also allows application to larger scale mapping of protein interactors and ligandable pockets in live cells for chemical libraries based on the PAL probe design principles mentioned above [Citation83,Citation84]. 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. eLife 5, e16950 (2016). However, many biological experiments would benefit from the ability to further increase multiplexing, to allow for biological replicates, time points, or treatment conditions to be analyzed in parallel. Toxicol. These common steps typically include: 1) selection of an appropriate, disease-relevant input material for the chemoproteomics experiment; 2) treatment of proteome with either free compound (for competitive workflows or workflows based on a broad specificity enrichment steps) or functionalized probe; 3) separation of proteins interacting with compound or probe in step 2) from background by e.g. Identifying metabolites alone does not give one the whole story about how a cell is signaling, what it is interacting with or under what cellular state it is in, but it can offer important clues. 14, 475486 (2015).
