Targeted Protein Degradation: Principles, Strategies, and Applications

Protein degradation is a general process to maintain cell homeostasis. The intracellular protein quality control system mainly includes the ubiquitin-proteasome system and the lysosome pathway. Inspired by the physiological process, strategies to degrade specific proteins have developed, which emerge as potent and effective tools in biological research and drug discovery. This review focuses on recent advances in targeted protein degradation techniques, summarizing the principles, advantages, and challenges. Moreover, the potential applications and future direction in biological science and clinics are also discussed.
