Application of PROTACs in Target Identification and Target Validation

PROTAC, as a novel therapeutic drug model, has received widespread attention from the academic and pharmaceutical industries. At the same time, PROTAC technology has led many researchers to focus on developing chemical biology tool properties due to its unique operating mechanism and protein dynamic regulatory properties. In recent years, the rapid development of PROTAC technology has gradually made it an essential tool for target identification and target validation. To further promote the application of PROTAC tools in drug discovery and basic medical sciences research, this review distinguished between target identification and target validation concepts. It summarized the research progress of PROTAC technology in these aspects.
