Despite Top Down proteomic methods promising to help resolve the isoform conundrum, and deciphering protein-isoforms at the purified protein level [Citation182], the community has yet to demonstrate the technologys utility in a robust manner, particularly at the level of sensitivity and throughput that are of general use for fast pathway analyses. PubMed Central 11, M111 010587 (2012). Collagen neoepitope peptides were identified by data dependent proteomics in an ex vivo cartilage explant model [Citation141]. Biol. Google Scholar. Chem. (ABPP). 11, 12451254 (2016). Apart from improved data analysis strategies, experimental workflows have been introduced to aid with this process, e.g., the SIM-PAL workflow which uses introduction of unique isotopic patterns to identify probe-labeled peptides in digested enriched samples [Citation87]. This method was initially implemented within the native instrument code, but later adapted to utilize the flexible vendor method file format [Citation20]. With the emergence of machine learning algorithms and real-time searching, more de novo sequencing approaches [Citation200] might come of age and more on the fly database generators. Natl Acad.

Chemoproteomics profiling of HDAC inhibitors reveals selective targeting of HDAC complexes. 80, 41754185 (2008). While global proteomic profiling to detect compound-induced changes in cellular protein abundance would not fall into the rather narrow definition of chemoproteomics used here, we will briefly mention recent applications in the context of compound target identification and mode of action elucidation. 17, 659664 (2010). These common steps typically include: 1) selection of an appropriate, disease-relevant input material for the chemoproteomics experiment; 2) treatment of proteome with either free compound (for competitive workflows or workflows based on a broad specificity enrichment steps) or functionalized probe; 3) separation of proteins interacting with compound or probe in step 2) from background by e.g. 63, 2030 (2020).
