PCAF acetylation of ISX at lysine residue 69 recruits acetylated bromodomain-containing protein 4 (BRD4) at lysine residue 332, and the resulting complex translocated into the nucleus and binds to EMT promoters, where acetylation of histone 3 at lysine residues 9, 14, and 18 initiates chromatin remodeling and subsequent gene expression in tumor cells [100]. The gene discussed is BRD4; the disease is neoplasm.
