Excited to share our new paper from the Buhrlage lab & Chowdhury labs! 🎉 We designed CAS-010, a selective, low nanomolar USP28 inhibitor that reduces p53 transcriptional activity, mimics p53 loss & disrupts 53BP1-USP28 binding, offering new insights into USP28 function. www.cell.com/cell-chemica...

Pharmacologic interrogation of USP28 cellular function in p53 signaling

Bratt, Kilgas et al. describe the SAR-driven design of CAS-010, a selective USP28 probe, alongside a control compound and an inhibitor-resistant mutant. They show that USP28 inhibition mimics p53 path...

Excited to share our latest publication, out in @science.org! We define a key role for the CST complex in double-strand break repair pathway choice. This study was conducted in close collaboration with the Sung lab at UT Health San Antonio. Congrats to @michelleswift.bsky.social and all authors!

CTC1-STN1-TEN1 controls DNA break repair pathway choice via DNA end resection blockade

Antagonistic activities of the 53BP1 axis and the tumor suppressor BRCA1-BARD1 determine whether DNA double-strand breaks (DSBs) are repaired by end joining or homologous recombination. We show that t...
