We study proteins that regulate chromosome structure and function. One approach we have developed involves obligately asymmetric nucleosomes, with which we can test the roles of individual histone tails in gene regulation and other chromosome functions (Ichikawa et al., eLife 6: e28836 (2017)).

We also study the cell biology and genomics of mammalian chromosome organization. We recently discovered that Chromatin Assembly Factor-1 (CAF-1) regulates protein accumulation and long-range DNA interactions at the nucleolus in human interphase cells. CAF-1 also regulates the protein composition of human mitotic chromosomes. These novel activities are mediated via regulation of the proliferation antigen Ki-67. (Smith et al., Mol. Biol. Cell 25: 2866-2881 (2014); Matheson and Kaufman, Chromosoma 125: 361-71 (2016); Mol. Biol. Cell 28: 21-29 (2017)). We are investigating how these proteins shape the structure of the human cell nucleus, and are also currently performing genome-scale analyses of mouse and human heterochromatin-nucleolar interactions. Ki-67 is particularly interesting not only because of its use as a clinical tumor marker, but because we find that it links cell cycle progression and heterochromatin maintenance in p21 checkpoint-proficient human cells (Sun et al. Mol. Cell. Biol. 37: e00569-16 (2017)).
