Inhibitory Smad7: Emerging Roles in Health and Disease
1 Jun 2011
Abstract excerpt
Smad7 is an inhibitory Smad protein that blocks Transforming Growth Factor-beta (TGF-β) signaling through a negative feedback loop, also capable of mediating the crosstalk between TGF-β and other signaling pathways. Smad7 mRNA and protein levels are upregulated after TGF-β signaling; subsequently, Smad7 protein binds TGF-β type I receptor blocking R-Smad phosphorylation and eventually TGF-β signaling. Because of...
