The activity of p300 relies on the fine-tuned interactome that involves a dozen p300 domains and hundreds of binding partners and links p300 to a wide range of vital signaling events. Here, we report a novel function of the ZZ-type zinc finger (ZZ) of p300 as a reader of histone H3. We show that the ZZ domain and acetyllysine-recognizing bromodomain of p300 play critical roles in modulating p300 enzymatic activity and its association with chromatin. The acetyllysine binding function of bromodomain is essential for acetylation of histones H3 and H4, whereas interaction of the ZZ domain with H3 promotes selective acetylation of the histone H3K27 and H3K18 sites. The ZZ domain of p300 mediates specificity of the adjacent HAT domain for histone H3.,Zhang Y, Xue Y, Shi J, Ahn J, Mi W, Ali M, Wang X, Klein BJ, Wen H, Li W, Shi X, Kutateladze TG Nat Struct Mol Biol. 2018 Sep;25(9):841-849. doi: 10.1038/s41594-018-0114-9.
