Ligands for E3 Ligase

A PROTAC (Proteolysis Targeting Chimeric Molecule) is a protein degrader comprised of a ligand for E3 ligase (E3 ligase binder), a linker and a ligand for target protein (target binder).The transfer of ubiquitin and degradation of the targeted protein will occur as a result of the connection between an E3 ligase and a target protein brought on by a PROTAC.

E3 ligases determine the specificity of the proteins by catalyzing the transfer of ubiquitin to the desired proteins. Cells have hundreds of E3 ligases, but only a small number of them have been successfully exploited in PROTACs, including VHL (the tumor suppressor protein for von Hippel-Lindau disease), CRBN (Cereblon), MDM2 (the mouse double minute 2 homologue), and IAP (inhibitor of apoptosis).
