We demonstrate that the inhibitory effect of Smad3 occurs via a novel antagonistic effect of Smad3 on C/EBP DNA-protein binding and activity
Nerlov et al., Curr Opin Cell Biol 2008
:
Finally, interaction with Smad proteins, which are accumulated in the nucleus upon TGFbeta or BMP signaling, may lead to the formation of C/EBP-Smad complexes and activation of Smad-C/EBPbeta coregulated promoters, while at the same time inhibiting other C/EBP dependent transcription
Hein et al., BMC molecular biology 2011
:
Thus SMAD3 appears to be a potential link between TGFß1 signaling and C/EBP regulated promoter activity
