Abstract
The functions of Myc in transformation and transactivation are countered by the suppressive actions of the Mad(Mxi1) family. Mad(Mxi1) proteins not only compete with Myc for dimerization to Max and binding to Myc/Max consensus sites but also recruit powerful repressors of gene expression. A prediction of the yin-yang relationship between Myc and Mad(Mxi1) families would be that the latter constitutes a new class of tumor suppressors. Here, we review the current literature on the Mad(Mxi1) family, with particular attention paid to the molecular mechanisms by which these proteins antagonize the actions of Myc in normal and neoplastic cells.
