SMAD3 pT179 is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. 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-beta superfamily.  Activated type I receptor phosphorylates receptor-activated Smads (R-Smads) at their c-terminal two extreme serines in the S-S-X-S motif, e.g. Smad2 and Smad3 proteins in the TGF-b pathway, or Smad1, Smad5 or Smad8 in the bone morphogenic protein or BMP pathway.  The phosphorylated R-Smads are 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.

Application Note

Anti-SMAD3 pT179 has been tested for use in ELISA and by western blot, and suitable by immunohistochemistry.  Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 48.1 kDa in size corresponding to human phosphorylated Smad3 protein by western blotting in the appropriate stimulated tissue or cell lysate or extract.


Anti-SMAD3 pT179 affinity-purified antibody is directed against the phosphorylated form of human Smad3 protein at the pT179 residue. The product was affinity purified from monospecific antiserum by immunoaffinity purification.  Antiserum was first purified against the phosphorylated form of the immunizing peptide.  The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide.  Reactivity occurs against human Smad3 pT179 protein and the antibody is specific for the phosphorylated form of the protein.   Reactivity with non-phosphorylated human Smad3 is minimal by ELISA and western blot.  Expect reactivity against phosphorylated Smad2.  Reactivity against other phosphorylated Smad family members is not known.  A BLAST analysis was used to suggest cross reactivity with Smad3 from human, mouse, rat, pig, dog, and marmoset based on 100% sequence homology with the immunogen.  Reactivity against homologues from other sources is not known.
