During the cell cycle, duplicated sister chromatids become physically connected during S phase through a process called sister-chromatid cohesion. Cohesion is terminated during the metaphase-to-anaphase transition to trigger sister-chromatid segregation. The establishment and dissolution of cohesion are highly regulated by the cohesin complex and its multitude of regulators. In particular, the cohesin regulator Wapl promotes the release of cohesin from chromosomes during both interphase and mitosis. Here, we describe in vitro protein binding assays between Wapl and a cohesin subcomplex, and cellular assays in human cells that probe the functions of Wapl in cohesin release.
