The mh1 domain of smad4 was shown to associate physically with ubc9, the ubiquitin carrier protein (e2) conjugating enzyme in sumoylation. In cultured cells, smad4 is modified by sumo-1 at the endogenous level. The sumoylation sites were identified as two evolutionarily conserved lysine residues, lys-113 and lys-159, in the mh1 domain. We found that the mutations at lys-113 and lys-159 did not alter the ability of smad4 to form a complex with smad2 and fast on the mix.2 promoter. Importantly, sumo-1 overexpression enhanced tgf-beta-induced transcriptional responses. These findings identify sumoylation as a unique mechanism to modulate smad4-dependent cellular responses |

We found that skp2, the f-box component of scfskp2, physically interacted with smad4 at the physiological levels. Several cancer-derived unstable mutants exhibited significantly increased binding to skp2, which led to their increased ubiquitination and accelerated proteolysis. These results suggest an important role for the scfskp2 complex in switching cancer mutants of smad4 to undergo polyubiquitination-dependent degradation. |

In this study, we characterize a novel nuclear protein, termed snip1 its principal mechanism of action appears to be through transcription by binding to cbp/p300 and interfering with the ability of these coactivators to interact with smad4 |

Our analysis of the regulation of dpc4 transcriptional activity by c-jun was consistent with the possibility that c-jun and dpc4 could interact and produce trans-activation of the 3tp-lux reporter. |

Our results suggest that map kinase can phosphorylate thr276 of smad4 and that phosphorylation can lead to enhanced tgf-beta-induced nuclear accumulation and, as a consequence, enhanced transcriptional activity of smad4. |

Whereas alk5 signalling is mediated by phosphorylation of smad2 and smad3 proteins, alk1 signalling is mediated by smad1, smad5, and smad8. Activated smads form a complex with the common smad (co-smad; smad4 in mammals) and shuttle into the nucleus. |
