BRD7 is an important protein tightly associated with Nasopharyngeal carcinoma (NPC). Overexpression of BRD7 inhibits NPC cell growth and cell cycle by transcriptionally regulating the cell cycle related genes. BRD7 contains a bromodomain that is found in many chromatin-associated proteins and in nearly all known nuclear histone acetyltransferases (HATs) and plays an important role in chromatin remodeling and transcriptional activation. Here, we report the solution structure of BRD7 bromodomain determined by NMR spectroscopy, and its binding specificity revealed by NMR titration with several acetylated histone peptides. We find that BRD7 bromodomain contains the typical left-handed four-helix bundle topology, and can bind with weak affinity to lysine-acetylated peptides derived from histone H3 with K9 or K14 acetylated and from histone H4 with K8, K12 or K16 acetylated. Our results show that BRD7 bromodomain lacks inherent binding specificity when binding to histones in vitro.
