The SysteMHC Atlas project. 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.

As mass spectrometry based proteomic technologies continue toward enabling single cell sensitivity, the era of next generation peptide and protein sequencing is imminent. Proteomics in drug development: the dawn of a new era? Unlike our genomic counterpart technologies, proteomics is not blessed with tools such as the polymerase chain reaction (PCR) to amplify low level biomaterial; instead, researchers must rely on advances in technologies to detect low level protein and peptide signals. In addition, these approaches offer an experimental framework to demonstrate target engagement in cells, model organisms and ultimately the patient in this case often using a more targeted detection and quantitation of the protein of interest to increase sensitivity and throughput. A key advantage common to all non-affinity enrichment-based approaches is that they do not require the time- and resource intensive generation and validation of an affinity tool compound and thus are ideal for higher throughput selectivity profiling.
