Sister chromatid cohesion is essential for chromosome segregation and is mediated by cohesin bound to DNA. Cohesin-DNA interactions can be reversed by the cohesion-associated protein Wapl, whereas a stably DNA-bound form of cohesin is thought to mediate cohesion. In vertebrates, Sororin is essential for cohesion and stable cohesin-DNA interactions, but how(More)
Sister chromatid cohesion depends on cohesin [1-3]. Cohesin associates with chromatin dynamically throughout interphase [4]. During DNA replication, cohesin establishes cohesion [5], and this process coincides with the generation of a cohesin subpopulation that is more stably bound to chromatin [4]. In mitosis, cohesin is removed from chromosomes, enabling(More)
