PROTACs represent a novel strategy for protein degradation that has gained prominence recently. Utilizing bifunctional molecules, PROTACs enable the targeted ubiquitination and subsequent degradation of proteins via the UPS. PROTACs can not only offer potential therapeutic applications for a variety of conditions, including cancer, immune dysregulation, viral infections, and neurodegenerative diseases, but also provide a unique chemical knockdown tool for biological research in a catalytic, reversible,
