The importance of cellular degradation kinetics for understanding mechanisms in targeted protein degradation

Targeted protein degradation has exploded over the past several years due to preclinical and early clinical therapeutic success of numerous compounds, and the emergence of new degradation modalities, which has broadened the definition of what a degrader is. The most characterized and well-studied small molecule degraders are molecular glues and proteolysis targeting chimeras (PROTACs). These degraders induce a ternary complex between a target protein, degrader, and E3 ligase component, resulting in ubiquitination and subsequent degradation of the target protein
