[[http://www.uniprot.org/uniprot/KAT2B_HUMAN KAT2B_HUMAN]] Functions as a histone acetyltransferase (HAT) to promote transcriptional activation. Has significant histone acetyltransferase activity with core histones (H3 and H4), and also with nucleosome core particles. Also acetylates non-histone proteins, such as ACLY. Inhibits cell-cycle progression and counteracts the mitogenic activity of the adenoviral oncoprotein E1A. In case of HIV-1 infection, it is recruited by the viral protein Tat. Regulates Tat's transactivating activity and may help inducing chromatin remodeling of proviral genes.<ref>PMID:8684459</ref> <ref>PMID:9707565</ref> <ref>PMID:10675335</ref> <ref>PMID:23932781</ref>
