Acetylated SMAD3 is active. 1 / 1

"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."
