SMAD9 or Mothers against decapentaplegic homolog 9 is a polypeptide that, as its name describes, is a homolog of the Drosophila gene: "Mothers against decapentaplegic". It belongs to the SMAD family of proteins, which belong to the TGFβ superfamily of modulators. Like many other TGFβ family members, SMAD9 is involved in cell signalling.When a bone morphogenetic protein binds to a receptor (BMP type 1 receptor kinase) it causes SMAD9 to interact with SMAD anchor for receptor activation (SARA).The binding of ligands causes the phosphorylation of the SMAD9 protein and the dissociation from SARA and the association with SMAD4. It is subsequently transferred to the nucleus where it forms complexes with other proteins and acts as a transcription factor
Human Mothers against decapentaplegic homolog 9 (SMAD9) ELISA Kit employs a two-site sandwich ELISA to quantitate SMAD9 in samples. An antibody specific for SMAD9 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySMAD9 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SMAD9 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of SMAD9 bound in the initial step. The color development is stopped and the intensity of the color is measured.
