At present, proteomics is used pre-clinically for target identification and characterization, drug candidate selection and characterization, and clinically for biomarker discovery and development. Using these principles, it is clear that early SCoPE MS data suffered from quantitative noise and inaccuracies (CV > 40%), but more recent data such as the iBASIL study (above) appears to be much higher quality.

The method was used to analyze 1294 plasma samples in a human weight loss study [Citation151]. As mass spectrometric sensitivity and multiplexing capabilities increase it is possible that carrier proteomes will become obsolete, but until that time research should proceed with caution as they collect and interpret data from methods that rely on carrier proteomes to enable deep proteome quantification.

Cell 169, 350360.e312 (2017). Antibodies to the major neoepitope identified in the cartilage explant were then used for immunoaffinity proteomics of human urine and synovial fluid from normal and osteoarthritis (OA) subjects. 18, 699710 (2011). Implementation of this approach improves data accuracy and allows for similar proteomic depth to be achieved in half of the analysis time [Citation29]. 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. ProTargetMiner as a proteome signature library of anticancer molecules for functional discovery. This is primarily due to the emergence of targeted protein degradation (TPD) as a novel modality where pharmacological intervention results in modulation of target protein levels by recruitment of a target of interest to a suitable E3 ligase component such as CRBN or VHL to induce proteasome-dependent degradation. 196, 801810 (2012). Mol. The availability of large-scale genetic and transcriptomic data has fueled our understanding of the prevalence of common cancer mutations.

Depending on the intended use, the requirements for biomarker validation can vary significantly. post-translational modifications, metabolite concentrations and proteinprotein interactions can also lead to an assay signal (reviewed in Prabhu [Citation117]). However, Ribo-seq results are more powerful when combined with proteomic analysis that detect the protein product of the translation event. Dual chemical probes enable quantitative system-wide analysis of protein prenylation and prenylation dynamics. From a target perspective this means that essentially any small molecule-binding event to a protein of interest can be functionalized, even if the binding event itself is silent. While chemoproteomics has made crucial contributions to the identification of recruitment modules for, e.g., E3 ubiquitin ligase components like CRBN [Citation75], it is the large scale identification of ligands for targets of interest where it will most likely be most impactful.
