Application of Thermal Proteome Profiling-based chemoproteomics to patient-derived samples, opening the door for clinical applications for target engagement and off-target identification. Am. 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). In addition, the reliable mapping of PAL-probe insertion sites remains a key challenge for this workflow to fulfill its full promise. Chem. J. This method was initially implemented within the native instrument code, but later adapted to utilize the flexible vendor method file format [Citation20].
