By using the yeast two-hybrid system, we also show that EVI1 (contained in its entirety in MDS1/EVI1 and AML1/MDS1/EVI1 ) physically interacts with SMAD3 , which is an intracellular mediator of TGF-beta1 signaling .
 ( protein: AML1/MDS1/EVI1, None) , ( protein: TGF-beta1, None) , ( protein: EVI1, None) , ( protein: SMAD3, None) , ( DNA: MDS1/EVI1, None)
