Bait protein expressed as a DNA binding domain (DBD) fusion and prey expressed as a transcriptional activation domain (TAD) fusion and interaction measured by reporter gene activation.

Heteromeric and homomeric interactions correlate with signaling activity and functional cooperativity of Smad3 and Smad4/DPC4.
Homologs of Drosophila Mad function as downstream mediators of the receptors for transforming growth factor beta (TGF-beta)-related factors. Two homologs, the receptor-associated Smad3 and the tumor suppressor Smad4/DPC4, synergize to induce ligand-independent TGF-beta activities and are essential mediators of the natural TGF-beta response. We now show that Smad3 and Smad4 associate in homomeric and heteromeric interactions, as assessed by yeast ... [more]
