Component of the HBO1 complex, which specifically mediates acetylation of histone H3 at 'Lys-14' (H3K14ac) and, to a lower extent, acetylation of histone H4. Component of the MOZ/MORF complex which has a histone H3 acetyltransferase activity. Through chromatin acetylation it may regulate DNA replication and may function as a transcriptional coactivator. Inhibits cell growth, induces a delay in S-phase progression and enhances Fas-induced apoptosis in an INCA1-dependent manner. Component of the HBO1 complex composed of KAT7/HBO1, MEAF6, ING5, and one scaffold subunit: complexes containing BRPF scaffold (BRPF1, BRD1/BRPF2 or BRPF3) direct KAT7/HBO1 specificity towards H3K14ac, while complexes containing JADE scaffold (JADE1, JADE2 and JADE3) mediate acetylation of histone H4. Component of the MOZ/MORF complex composed at least of ING5, KAT6A, KAT6B, MEAF6 and one of BRPF1, BRD1/BRPF2 and BRPF3. Interacts with H3K4me3 and to a lesser extent with H3K4me2. Interacts with EP300 and p53/TP53. Interacts with INCA1. Localizes to transcription start sites. The PHD-type zinc finger mediates the binding to H3K4me3. May be due to a competing acceptor splice site. Belongs to the ING family.
