Structural and Molecular Insight into the PWWP1 Domain of NSD2 from the Discovery of Novel Binders Via DNA-Encoded Library Screening

NSD2 is a key epigenetic regulator and has received considerable attention as a drug target due to its well-documented role in tumorigenesis. We report here a DNA-encoded library screen targeting the PWWP1 domain of NSD2 from which we discovered novel, potent, and selective binders. Furthermore, these compounds were used to develop a novel crystal system, increasing our understanding of the folding of this domain. Together, these results provide a solid molecular and structural basis for the further study of the PWWP1 domain of NSD2 as a cancer drug target.
