A practical guide to approaching biased agonism at G protein coupled receptors. 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. Challenges remain for nanopore sequencing, particularly the discrimination of post-translationally modified amino acid residues. One of these substrates, Dickkopf-related protein 3 (DKK3), was used as a pharmacodynamic biomarker in Phase 1 trials of an anti-HtrA1 Fab (Fab15H6.v4.D221). Cell Biol. Laumont, C.

USA 106, 46174622 (2009). Biological matrices where the dramatic range of protein concentrations poses analytical challenges are whole blood or serum, where antibodies may be present at concentrations as high as 1 mg/nL but immunomodulatory proteins such as cytokines or chemokines, popular targets for biological exploration or biomarkers of disease etiology are often present at a mere ng/mL concentration [Citation12]. 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. 14, 475486 (2015). 28, 413.e17 (2021). Substrates of type I PMRT were identified using a methylated arginine enrichment proteomic strategy (MethylScan) [Citation146]. Proteomics. Figure 1.
