Component of the NuA4 histone acetyltransferase complex which is involved in transcriptional activation of selected genes principally by acetylation of nucleosomal histone H4 and H2A. The NuA4 complex is also involved in DNA repair. Involved in cell cycle progression and meiosis (By similarity). Interacts with H3K4me3 and to a lesser extent with H3K4me2. Component of the NuA4 histone acetyltransferase complex. The PHD-type zinc finger mediates the binding to H3K4me3. Belongs to the ING family.
