Smad3 (also known as Mothers against decapentaplegic homolog 3 Mothers against DPP homolog 3, Mad3, hMAD-3, JV15-2 or hSMAD3) is a transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinase.
These activators exert diverse effects on a wide array of cellular processes.
The Smad proteins mediate much of the signaling responses induced by the TGF-ß superfamily.
Briefly, activated type I receptor phosphorylates receptor-activated Smads (R-Smads) at their c-terminal two extreme serines in the SSXS motif, e.g.
Smad2 and Smad3 proteins in the TGF-b pathway, or Smad1, Smad5 or Smad8 in the BMP pathway.
Then the phosphorylated R-Smad translocated into nucleus, where they regulate transcription of target genes.
Based on microarray and animal model experiments, Smad3 accounts for at least 80% of all TGF-B mediated response.
