Background
SMAD3 (Smad3) is TGF-β-pathway receptor-activated R-Smad highly homologous to Smad2, transducing TGF-β and Activin signals for cell-cycle arrest, EMT, fibrosis and immune regulation. TGF-β type-I receptor phosphorylates C-terminal SSXS motif of Smad3. Activated Smad3 heterodimerizes with Smad4, translocates to nucleus and binds target-gene promoters to execute TGF-β transcriptional responses. Smad3 shares partial redundancy with Smad2 yet exhibits distinct tissue preference and target-gene selectivity, and is central to organ fibrogenesis. It mediates anti-proliferative effects in early-stage tumors and promotes invasion-metastasis at advanced stages.
