1 Here, using Bcl6 -/- knockout mice, HEK293A and HCT116 p53 -/- cells, and site-directed mutagenesis, we found that BCL6 interacts with p53 and thereby inhibits acetylation of Lys-132 in p53 by E1A-binding protein p300 (p300), a modification that normally occurs upon DNA damage-induced cellular stress and whose abrogation by BCL6 diminished transcriptional activation of p53 target genes, including that encoding caspase-1. Lysine tumor protein p53 Homo sapiens
