Suppressor mutation analysis combined with 3D modeling explains cohesin’s capacity to hold and release DNA [Genetics]

Cohesin is a fundamental protein complex that holds sister chromatids together. Separase protease cleaves a cohesin subunit Rad21/SCC1, causing the release of cohesin from DNA to allow chromosome segregation. To understand the functional organization of cohesin, we employed next-generation whole-genome sequencing and identified numerous extragenic suppressors that overcome either inactive...
