Signaling events leading to transcriptional activation initiated by members of the TGF-beta superfamily are known to be mediated by SMAD proteins. Biological activities mediated by SMADs include cell growth and morphogenesis, development, and immune response. Activation by TGF-b is mediated by Smad2 and Smad3 while activation by bone morphogenetic protein (BMP) is mediated by Smad 1 and Smad 5. In contrast to the activating effects of these Smad proteins, Smad6 and Smad7, whose expression is also induced by ligand binding, appear to function as negative regulators of TGF-b superfamily signaling pathways.
