Description: 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. 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- beta 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- beta -mediated response.

Specificity: This affinity-purified antibody is directed against human Smad3 protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification. ELISA and western blot show equivalent reactivity against phosphorylated and non-phosphorylated human Smad3. Expect reactivity against Smad1 and Smad5. Negligible reactivity is seen against other Smad family members. A BLAST analysis was used to suggest cross reactivity with Smad3 from human, Xenopus laevis, Xenopus tropicalis, zebrafish, rat, mouse, swine, bovine and chicken based on 100% sequence homology with the immunogen. Reactivity against homologues from other sources is not known.

Application Details

Application Notes: This affinity purified antibody has been tested for use in ELISA, immunohistochemistry and by western blot. Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 48 kDa in size corresponding to Smad3 protein by western blotting in the appropriate stimulated tissue or cell lysate or extract. This reagent reacts equally to phosphorylated and non-phosphorylated Smad3 by ELISA and western blotting.
