Gene Information
human ... SMAD4(4089)
General description
The gene SMAD4 (mothers against decapentaplegic homolog 4) is mapped to human chromosome 18q21.1. The protein localizes in the cytoplasm and nucleus. SMAD4 is also referred as DPC4 (deleted in pancreatic carcinoma).
Immunogen
Mothers against decapentaplegic homolog 4 recombinant protein epitope signature tag (PrEST)
Application
All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.
The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions
Upon TGFβ (transforming growth factor β) activation, SMAD (mothers against decapentaplegic homolog) proteins are responsible for transcription activation in the nucleus. SMAD4 is a crucial protein of TGFβ signaling. It promotes association of SMAD2/4 to DNA and helps SMAD1/2 in transcription stimulation. Mutations in SMAD4 are linked with juvenile polyposis syndrome, hereditary haemorrhagic telangiectasia and Myhre syndrome. In renal cell carcinoma, it activates forkhead box protein H1 and thereby inhibits the progression of the carcinoma. SMAD4 is considered as a tumor suppressor protein.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

SMAD4 has been suggested to inhibit the activity of the WNT/β-catenin signaling pathway in cancer. However, the mechanism by which SMAD4 antagonizes WNT/β-catenin signaling in cancer remains largely unknown. Aurora A kinase (AURKA), which is frequently overexpressed in cancer, increases

We have reported previously that PDK1 physically interacts with STRAP, a transforming growth factor-beta (TGF-beta) receptor-interacting protein, and enhances STRAP-induced inhibition of TGF-beta signaling. In this study we show that PDK1 coimmunoprecipitates with Smad proteins, including Smad2, Smad3, Smad4, and
