Excited to share our new preprint! Using D2B “degrader-first” screening, we uncovered two unexpected routes to protein degradation involving DCAF11/16 and CRL3–SPOP. Our work adds to growing evidence that TPD can extend far beyond canonical PROTAC mechanisms. chemrxiv.org/doi/abs/10.2...

Findings from Prof. Chris Parker's lab show that post-translational modifications (PTMs) can determine whether proteins bind drug-like molecules. Published in Nature Chemical Biology, the study identified 400+ proteins whose druggability depends on modification state. More: ow.ly/3OQj50YVecw

Insightful perspective by the group of Ben Cravatt with first author @xiaoyuzhang.bsky.social in @nchembio.bsky.social. They discuss reasons, why expanding the repertoire of E3s for TPD has converged on few "frequent hitters" and how additional E3 targets could be identified. doi.org/10.1038/s415...
