MeSH definition : A catalytic subunit of the NuA4 histone acetyltransferase complex that functions in
transcriptional activation of genes by acetylation of nucleosomal HISTONES H4 and
H2A, altering nucleosome-DNA interactions and interaction of the modified histones
with other activating transcription factors. It may control gene expression changes
associated with oncogene and proto-oncogene mediated growth induction, tumor suppressor
mediated growth arrest; CELL AGING; APOPTOSIS; and DNA REPAIR. It is polyubiquitinated
and degraded during HIV-1 infection through its interaction with the viral TAT PROTEIN.;
