CETSA beyond soluble targets: a broad application to multipass transmembrane proteins. Nature Communications An alternative strategy is to analyze candidate transcript expression within databases specialized in normal tissue expression, such as the Genotype-Tissue Expression (GTEX) project. Historically, the focus has been on identification of functionally relevant interactions such as efficacy target identification where complementary, in particular genetic approaches were required to prioritize physical interactors identified by chemoproteomics hits by functional relevance (and vice versa since genetic screening hits often include additional components of the target biology network).

Annu. Techniques such as BioID [Citation189], APEX [Citation190] and FLARE [Citation191] have emerged as extremely useful tools to study more transient intracellular interactions, however, there are limitations to their utility on occasion as they require protein tagging, hence potentially changing native biological properties of the target protein.

In the near future, it is possible that a sufficiently sophisticated deep learning algorithm could consider an MS spectrum, retention time, and collisional cross section to predict a peptide sequence without performing a database search. At present, proteomics is used pre-clinically for target identification and characterization, drug candidate selection and characterization, and clinically for biomarker discovery and development.
