Gene Information

General description

SMAD3 (homologues of the Drosophila protein, mothers against decapentaplegic (Mad) and the Caenorhabditis elegans protein) is located on human chromosome 15q22. SMAD2 (SMAD family member 2) is also called as MADR2 (substrate of the TGFβ receptor). It is located on human chromosome 18q21. Smad2/3 belongs to the mothers against Dpp (MAD) related family of proteins. SMAD2 has two highly conserved amino and carboxyl-terminal domains (MH1 and MH2 domains) but has no known structural motifs.

Immunogen

The antiserum was produced against synthesized peptide derived from human Smad2/3 around the phosphorylation site of Thr8.

Immunogen Range: 1-50

Application

Anti-phospho-Smad3 (pSer425) antibody has been used in western blotting.

Biochem/physiol Actions

SMAD (homologues of the Drosophila protein, mothers against decapentaplegic (Mad) and the Caenorhabditis elegans protein) proteins play an important role in the intracellular signalling of transforming growth factor β (TGFβ). Reduction in the phosphorylation level of Smad3 helps autophagy to control the endothelial-mesenchymal transition. In human arterial smooth muscle cells, suppressing siRNA of SMAD3 improves the viability of cells. Mutations in SMAD2 (SMAD family member 2) results in arterial aneurysms and dissections. Upregulation of Smad2 blocks the multiplication of gingival epithelial cells. It plays an important role in TGF-β (transforming growth factor β)/activin signaling pathways. Smad2 positively and negatively controls TGFβ-dependent transcription with the help of forkhead DNA-binding protein FAST2.
