Degrader Building Blocks

Targeted protein degradation can be achieved using heterobifunctional small molecule degraders, which are modular in design, comprising binding moieties for an E3 ubiquitin ligase and a target protein joined by a linker. Below you will find a toolbox of degrader building blocks to support targeted protein degradation research and development.

    Heterobifunctional small molecule degraders (e.g. PROTACs™) induce targeted protein degradation and are modular in design, consisting of three covalently linked components:

    • E3 ubiquitin ligase ligand
    • Linker
    • Ligand for a target protein of interest

    They have successfully been designed and utilized to induce targeted degradation of a variety of different proteins, including bromodomain-containing proteins, ligases, kinases, and RTKs. Application of this approach to achieve knockdown of further targets is currently an area of active research.

    Tocris provides building blocks to support Degrader research and development. Our range of Degrader components have functional handles for easy conjugation to ligands/linkers of interest. Included in this range are the most effective and commonly used E3 ubiquitin ligase ligands, functionalized at positions known not to interfere with binding affinity. E3 ligase ligands conjugated to common linker groups are also supplied.
