Ligands for E3 Ligase

Ligands for E3 ligase are pivotal molecules in the field of targeted protein degradation, a promising therapeutic strategy in drug development. E3 ligases are enzymes that facilitate the transfer of ubiquitin from an E2 ubiquitin-conjugating enzyme to specific substrate proteins, marking them for degradation via the ubiquitin-proteasome system. By developing ligands that can specifically bind to E3 ligases, researchers can harness or enhance their activity to selectively degrade malfunctioning or disease-associated proteins. This approach is particularly significant in cancer and neurodegenerative diseases, where protein homeostasis is often disrupted. The development of such ligands can lead to highly specific and effective therapies with potentially fewer side effects compared to traditional drugs.
