Inducible Protein Degradation to Understand Genome Architecture.

We review exciting recent advances in protein degradation, with a focus on chromatin structure. In our analysis of the literature, we highlight studies of kinetic control of protein stability for cohesin, condensin, ATP-dependent chromatin remodeling, and pioneer transcription factors. With new connections emerging between chromatin remodeling and genome structure, we anticipate exciting developments at the intersection of these topics to be revealed in the coming years. Moreover, we pay special attention to the 20-year anniversary of PROTACs, with an overview of E3 ligase/target pairings and central questions that might lead to the next generation of PROTACs with an expanded scope and generality. While steady-state experimental measurements with constitutive genome editing are impactful, we highlight complementary approaches for rapid kinetic protein degradation to uncover early targeting functions and to understand the central determinants of genome structure-function relationships.
