摘要
The centromere of a chromosome contains regions of heterochromatin that have diverse roles during chromosome segregation. Here, the authors demonstrate in fission yeast that during mitosis, the main function for centromeric heterochromatin is to recruit cohesin. In contrast, during meiosis, the most important function for heterochromatin is to recruit the cohesin protector shugoshin to centromeres. This function is conserved in human cells.
