The NuA4 HAC may be required for activating transcription programmes of oncogene and proto-oncogene mediated growth induction, tumour suppressor-mediated growth arrest/replicative senescence, apoptosis, and DNA repair. Post-translational modifications include sumoylation, phosphorylation, ubiquination and autoacetylation. |
