Targeted Protein Degradation

Targeted Protein Degradation (TPD) refers to the use of heterobifunctional small molecule "degraders" (e.g. PROTACs™) to achieve knockdown of target proteins within cells. These small molecules consist of binding moieties for an E3 ubiquitin ligase and a target protein joined by a linker. The binding of both moieties results in the formation of a ternary complex between target protein and E3 ligase, leading to polyubiquitination of the target protein, its recognition by the proteasome and subsequent degradation.

Tocris has a range of Active Degraders targeting different proteins, as well as a toolbox of Degrader Building Blocks to support TPD research and development.

Figure 1: Schematic showing the catalytic mode of action of heterobifunctional degrader molecules. Degraders initiate the formation of a ternary complex between an E3 ubiquitin ligase and a target protein which results in polyubiquitination of the target protein, its recognition by the proteasome and subsequent degradation. Degraders act catalytically by repeatedly engaging and directing the ubiquitination of target molecules.

Targeted Protein Degradation Poster

Degraders (e.g. PROTACs) are bifunctional small molecules, that harness the Ubiquitin Proteasome System (UPS) to selectively degrade target proteins within cells. They consist of three covalently linked components: an E3 ubiquitin ligase ligand, a linker and a ligand for the target protein of interest. Authored in-house, this poster outlines the generation of a toolbox of building blocks for the development of Degraders. The characteristics and selection of each of these components are discussed.
