NuA4/Tip60, a complex with diamond ring architecture, is required for regulatory and repairing processes. Prof. CAI Gang and Prof. Jacques Côté’s team reports the 4.7 Å structure of the yeast NuA4/TIP60 complex, which elucidates the detailed architecture and molecular interactions between NuA4 subunits. Related study is published online in Nature Communications on March 19th.
