This study identifies Ki-67 as a regulator of nucleolar shape through its amphiphilic properties that anchor chromatin, linking nucleolar morphology to genome organization.

The paper investigates how the charge distribution on Ki-67 affects RNA-mediated inter-chromosome attraction during cell division.

This study shows Ki-67 switches from repelling to attracting chromosomes during mitotic exit, forming a liquid-like coat that drives chromosome clustering through phase separation.
