The precise segregation of chromosomes is critical for the proliferation and development of living organisms. Defects in this process can result in tumorigenesis and hereditary diseases. The four-subunit cohesin complex plays an essential role in chromosome segregation and genome integrity. Recently, we reported that the association of cohesin with centromeres and chromosome arms is differentially regulated by the ATP-dependent RSC chromatin-remodeling complex. Here, we propose two models to explain why the cell should have evolved special mechanisms for centromeric and sister arm cohesion and why RSC differentially regulates these processes.
