The PROTAC molecule consists of a target protein ligand and an E3 ubiquitin ligase ligand, with a linker binds them together. The ligand for target protein will lead to attachment of a PROTAC to the proteins of interest for ubiquitin and subsequent degradation.

Target proteins are usually proteins whose overexpression or accumulation may play important roles in the progress of diseases. Numbers of PROTACs have been developed to degrade kinases (such as MEK, KRAS, CDK and Bcr/Abl), transcription factors (such as p53, STAT, RAR, ER and AR), epigenetic tools (such as HDAC and BET bromodomain) and E3 ligase themselves (such as MDM2).
