RiceNetDB is currently the most comprehensive regulatory database on Oryza Sativa
based on genome annotation. It was displayed in three levels: GEM, PPIs and GRNs
to facilitate biomolecular regulatory analysis and gene-metabolite mapping.
Required for the function of some acidic activation domains, which activate transcription from a distant site. The exact mechanism of action is not yet known. ADA2 and GCN5 function to acetylate nucleosomes, opening up the promoter region (By similarity).
