This article reports the first draft of the human proteome. Accordingly, the general workflow has been applied successfully not only to target deconvolution for bioactive compounds such as for nimbolide (E3 ligase RNF114) [Citation93] or dimethyl fumarate (kinase complexes PKC-CD28 [Citation94] and IRAK44-Myd88 [Citation95]) but also to large scale mapping of protein interactors and ligandable pockets in living cells using electrophile libraries [Citation96]. the identification of phenyl hydroxylase as an off-target of the HDAC inhibitor panobinostat [Citation105]. Target identification and mechanism of action in chemical biology and drug discovery. Rep. 10, 5324 (2020). Chemoproteomics encompasses a number of workflows that aim to identify and characterize drug-target interactions in cells or cell-derived samples such as cell lysates or enriched subcellular fractions. A number of different techniques have been implemented to feed the protein through the pore including attachment of a DNA tag [Citation34], utilization of an unfoldase [Citation35], or the use of adhering negative ionic detergents [Citation36]. 9, 232240 (2013). Contact Dermat. Schirle, M. & Jenkins, J. L. Identifying compound efficacy targets in phenotypic drug discovery. In addition, the increased meta-analysis of chemoproteomics data and integration with other MoA-relevant datasets will be crucial to further facilitate hit calling and prioritization of target hypotheses for time- and resource-consuming in-depth validation experiments. 15, e8438 (2019). 176, 145151 (2007). The fact that chemoproteomics identifies physical interactions independent of functional relevance turns from being a disadvantage in the context of efficacy target identification into an advantage, as it provides the most comprehensive picture of both functional and silent compound-protein interactions that can be exploited using different modalities.

If the protein products of these translation events are rapidly turned over, it stands to reason that they would be more readily presented on the cell surface. Finally, global proteomic profiling has seen renewed interest in the context of compound target identification and mechanism of action studies.
