Structural studies yield important insights into protein function, the "druggability" of protein targets for drug discovery, and drug design. Advancing targeted protein degradation for cancer therapy. Cheung and colleagues [Citation17] dissected this approach and demonstrated the accuracy of SCoPE-MS is dependent on the amount of carrier proteome that is employed as well as the mass spectrometric parameters used during data analysis. As proteins constitute the majority of targets in drug development, these workflows have become indispensable at various stages of the drug discovery process: in phenotypic or cell-based drug discovery, where screening of large compound libraries in a cellular or organismal model of disease is used to identify chemical starting points, chemoproteomics can generate target hypotheses and in extension provide information about the mechanism of action (MoA) by which the compound exerts its phenotypic effect.
