From the BEST document, validation, for biomarkers and clinical outcome assessments, is a process to establish that the performance of a test, tool, or instrument is acceptable for its intended purpose. It is important to demonstrate that the test measures what it was intended to measure (analytical validation) and that the biomarker (through its test) has the ability to predict or measure the relevant clinical concept. Messner, C. B. et al. Science 367, 10911097 (2020). 196, 801810 (2012). The use of biomarkers in drug development has increased in recent years, and a recent analysis reported that more than half of recently approved drugs were supported by biomarker data [Citation137]. Chemical proteomics can also be dened as bespoke afnity capture or afnity chromatography. Rev. A mammalian protein targeted by G1-arresting rapamycinreceptor complex. With rapid advancements in the RNA sequencing field, proteogenomics has been shown to be a power tool allowing the generation of customized protein sequence databases using genomic and transcriptomic information. 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. The study showed that these two complementary approaches targeting different components of the proteome could have significant advantages for biomarker candidate discovery. developed a robust high throughput capillary flow DIA method capable of analyzing 31 plasma proteomes/day, measuring over 500 proteins/sample and used this method to analyze the DioGenes cohort of 1508 samples [Citation153]. Am. Covering an even larger target spectrum are probes that target solvent exposed reactive amino acids in general, e.g. While these workflows are used so far predominantly for cysteine-targeting compounds, they can per se be applied to any reactive amino acids for which pan-reactive probes are available. Multiplexed proteome dynamics profiling reveals mechanisms controlling protein homeostasis.
