Figure 1: Overview of BRD4/H4 K12acK16ac nucleosome structure.

(a) Cryo-EM map and (b) cartoon representation of the BRD4-S/H4 K12acK16ac nucleosome complex showing how the BRD4 BD1 (pink) interacts with the nucleosome. The modeled histone H4 tail residues 11–16 are shown as a thicker gold line. The locations of the BRD4-S structured domains are shown below together with the color key for the figures.
