The mechanism and chemistry of peptide/small molecule-based PROTACs and RNA-PROTAC (A) PROTACs selectively degrade pathogenic proteins based on the ubiquitin-proteasome system that consists of specific enzymes (ubiquitin-activating enzyme E1, ubiquitin-conjugating enzyme E2, and ubiquitin ligase E3) modifying proteins with ubiquitin and 26S proteasomes degrading the ubiquitin-tagged proteins. Conventional PROTAC contains a small-molecule or peptidic ligand for the protein of interest (POI), a ligand of E3 ligase, and a linker connecting the latter two. RNA-PROTAC utilizes an oligoribonucleotide to recognize an RNA-binding protein (RBP, for example, Lin28) based on an endogenous RNA-protein interaction, thereby enhancing the degradation of the RBP. (B) Given the chemical structure of the moiety that recognizes the POI, PROTACs can be peptide-based, small molecule-based, and/or nucleotide-based. The graphics show the chemical structures of the peptide-based STAT3 PROTAC SD36, the small molecule-based BRAFV600E PROTAC P4B, and the Lin28 RNA-PROTAC ORN3P1.
