Summary

Histone H3 levels increase at centromeres during S phase, new CENP-A replaces H3 during G2. 

Centromere DNA drives H3 cell cycle dynamics independent of centromere proteins and the eviction of H3 is coincident with recruitment of elongating RNAPII. We propose a model in which RNAPII-coupled chromatin remodeling promotes replacement of H3 with CENP-A nucleosome
