Synovial sarcoma (SS) is a difficult-to-treat cancer, driven by the fusion oncoprotein SS18::SSX. SS18::SSX alters the BAF (mammalian SWI/SNF) chromatin remodelling complex to create an oncogenic transcriptome. Here, the authors identify SS18::SSX-driven SMARCE1 SUMOylation as a therapeutic vulnerability in SS and show that SUMOylation inhibition stabilizes the cBAF complex, inducing cell death and sensitization of SS to chemotherapy.
