DNA bridges, thin DNA connections that link daughter cells after division, threaten genome integrity and can trigger catastrophic chromosome rearrangements. A new study proposes that ESCRT-III proteins form protective assemblies around fragile ultrafine DNA bridges, revealing an unexpected role for these membrane-remodeling complexes in genome protection.

Abstract Methods to systematically monitor protein complex dynamics are needed. We introduce serial ultrafiltration combined with limited proteolysis-coupled mass spectrometry (FLiP–MS), a structural proteomics workflow that generates a library of peptide markers specific to changes in PPIs by probing differences in protease susceptibility between complex-bound and monomeric forms of proteins.
