Smad proteins are crucial for the intracellular signaling of transforming growth factor-beta (TGF-beta). Upon their receptor-induced activation, Smad proteins are phosphorylated and translocated to the nucleus to activate the transcription of a select set of target genes. Here, we show that the co-activator p300/CBP bound and acetylated Smad3 as well as Smad2 in vivo, and that the acetylation was stimulated by TGF-beta.A major acetylation site of Smad3 by p300/CBP is Lys-378 in the MH2 domain (Smad3C) known to be critical for the regulation of transcriptional activity. |

Macromolecular translocation inhibitor II (MTI-II), which was first identified as an in vitro inhibitor of binding between the highly purified glucocorticoid receptor (GR) and isolated nuclei, is an 11.5-kDa Zn2+-binding protein that is also known as ZnBP or parathymosin. MTI-II Enhances GR-dependent Transcription through Its Acidic Domain. MTI-II Enhances GR-dependent Transcription in Cooperation with SRC-1 and p300 in Vivo. CBP and p300 Coprecipitate with MTI-II in a Glucocorticoid Hormone-dependent Manner. Immunoprecipitation analysis showed that in the presence of glucocorticoid hormone, p300 and CREB-binding protein are coprecipitated with MTI-II. Furthermore, the knockdown of endogenous MTI-II by RNAi reduces the transcriptional activity of GR in cells. |

P53 is stabilized by the binding of p300 to the oncoprotein E1A, suggesting that p300 regulates p53 degradation. Purified p300 exhibited intrinsic ubiquitin ligase activity that was inhibited by E1A. In vitro, p300 with MDM2 catalyzed p53 polyubiquitination, whereas MDM2 catalyzed p53 monoubiquitination. E1A expression caused a decrease in polyubiquitinated but not monoubiquitinated p53 in cells. Thus, generation of the polyubiquitinated forms of p53 that are targeted for proteasome degradation requires the intrinsic ubiquitin ligase activities of MDM2 and p300. |

Once released from associated repressors, MEF2 is bound by the p300 coactivator, which possesses histone acetyltransferase activity. Thus, the net result of CaMK signaling to MEF2 complexes is increased histone acetylation (Ac), which relaxes chromatin and stimulates MEF2 target gene transcription. |
