We demonstrate that both smad2 and smad3 are acetylated by the coactivators p300 and cbp in a tgfb-dependent manner. the p300-dependent acetylation of smad3 was attenuated when lys19 was mutated, whereas mutation of lys20 had no effect, suggesting that lys19 is acetylated also in smad3. |

The closely related CBP and p300 proteins are also important coactivators for Smad activity. CBP and p300 act as coactivators of several transcription factors by bringing the sequence-specific activators within proximity of the general transcription machinery and by modifying the chromatin structure through histone acetylation.In response to TGF-b, Smad3 associates with CBP/p300 and TGF-b-induced C-terminal phosphorylation of Smad3 promotes this association. This association with CBP/p300 is likely to be essential for transcriptional activity of Smad3. |

We demonstrate that both smad2 and smad3 are acetylated by the coactivators p300 and cbp in a tgfbeta-dependent manner. To identify the specific lysine residue acetylated by p300, lys19, and lys20 in smad2(fl) were mutated individually and subjected to p300-mediated acetylation following expression in 293t cells. Mutation of lys19 blocked the p300-mediated acetylation of smad2(fl), whereas mutation of lys20 had no effect (fig. 2b), suggesting that lys19 is the preferred site for p300-mediated acetylation of smad2(fl). |

KMT2D associates with WRAD (WDR5, RbBP5, ASH2L, and DPY30), NCOA6, PTIP, PA1, and H3K27 demethylase UTX in one protein complex. It acts as a scaffold protein within the complex and is responsible for maintaining the stability of UTX. KMT2D is a major mammalian H3K4 mono-methyltransferase and co-localizes with lineage determining transcription factors on transcriptional enhancers. It is required for the binding of histone H3K27 acetyltransferases CBP and p300 on enhancers, enhancer activation and cell-type specific gene expression during differentiation. |

Previous studies have established that YY1 interacts with histone acetyltransferases p300 and CREB-binding protein (CBP) and histone deacetylase 1 (HDAC1), HDAC2, and HDAC3. Here, we present evidence that the activity of YY1 is regulated through acetylation by p300 and PCAF and through deacetylation by HDACs. YY1 was acetylated in two regions: both p300 and PCAF acetylated the central glycine-lysine-rich domain of residues 170 to 200, and PCAF also acetylated YY1 at the C-terminal DNA-binding zinc finger domain. Acetylation of the central region was required for the full transcriptional repressor activity of YY1 and targeted YY1 for active deacetylation by HDACs. |

The current results provide the first insights into the regulation of EpCAM expression, which is regulated negatively by TNFalpha and TPA through the activation of NF-kappaB. The repression may rely on the competition of NF-kappaB for p300/CBP histone acetyl transferase activity, because the overexpression of p300 reverts TNFalpha effects. |

Here we show that E2F-5 is phosphorylated by the cyclin E-Cdk2 complex, which functions in the late G1 phase, but not by the early-G1-phase-acting cyclin D-CDK complex. A phosphorylation site in the trans-activation domain of E2F-5 stimulates transcription and cell-cycle progression by the recruitment of the p300/CBP family of co-activators, whose binding to E2F-5 is stabilized upon phosphorylation by cyclin E-Cdk2. These results indicate that phosphorylation of E2F-5 at the CDK site at position 251 by cyclin E–Cdk2 augments transcription by enhancing the interaction of E2F-5 with p300/CBP co-activator proteins. |

CBP and p300, but Not P/CAF, Enhance EKLF Trans-activation in Erythroid Cells. We find that EKLF is an acetylated transcription factor, and that it interacts in vivo with CBP, p300, and P/CAF. However, its interactions with these histone acetyltransferases are not equivalent, as CBP and p300, but not P/CAF, utilize EKLF as a substrate for in vitro acetylation within its trans-activation region. |
