Outcomes: Histone deacetylase three (HDAC3) regulates cyclin A deacetylation. Conclusion: HDAC3 regulates cyclin A stability by modulating cyclin A acetylation. Significance: HDAC3 regulates cell cycle progression by controlling cyclin A levels. PCAF and GCN5 acetylate cyclin A at precise lysine residues targeting it for degradation at mitosis. We report here that histone deacetylase three (HDAC3) straight interacts with and deacetylates cyclin A. HDAC3 interacts with a domain integrated inside the very first 171 aa of cyclin A, a region involved inside the regulation of its stability. In cells, overexpression of HDAC3 reduced cyclin A acetylation whereas the knocking down of HDAC3 increased its acetylation. In addition, reduction of HDAC3 levels induced a decrease of cyclin A that may be reversed by proteasome inhibitors. These outcomes indicate that HDAC3 is in a position to regulate cyclin A degradation through mitosis by way of proteasome. Interestingly, HDAC3 is abruptly degraded at mitosis also through proteasome hence facilitating cyclin A acetylation by PCAF/GCN5, that will ta.
