A bromodomain-DNA interaction facilitates acetylation-dependent bivalent nucleosome recognition by the BET protein BRDT

Many chromatin modifying proteins, including BRDT, contain bromodomains, which are known to interact with nucleosomes. Here, the authors find that BRDT interacts with nucleosomes via only one of its two bromodomains, and that the interaction involves contacts with DNA as well as acetylated histones.
