- 关于 Tocris
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.

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.
