Physical and Functional Interaction of SMADs and p300/CBP
Open accessAbstract
SMADs are transforming growth factor beta (TGF-beta) receptor substrates and mediators of TGF-beta transcriptional responses. Here we provide evidence that the coactivators p300 and CBP interact with Smads 1 through 4. The biological relevance of this interaction is shown in vivo by overexpression of the adenovirus E1A protein and mutant forms of E1A that lack p300-binding sites. Wild-type E1A, but not the mutants, inhibits SMAD-dependent transcriptional responses to TGF-beta. E1A also inhibits the intrinsic transactivating function of the Smad4 MH2 domain. In addition, overexpression of p300 enhances SMAD-dependent transactivation. Our results suggest a role for p300/CBP in SMAD-mediated transcriptional activation and provide an explanation for the observed ability of E1A to interfere with TGF-beta action.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
