Anti-Madh9 antibodies are used in antigen-specific immunodetection in biological samples. The target Madh9 is a known alias name of the protein SMAD family member 9, encoded by the SMAD9 gene in humans. This 467-amino acid residue protein is known to be involved in the morphogenesis of anatomical structure and cell differentiation, among other biological processes. It is localized to the nucleus and cytoplasm of the cell and features phosphorylated post-translational modifications. In terms of tissue expression, it is found to be expressed in the heart, brain, placenta, lung, skeletal muscle, prostate, testis, ovary and small intestine. Other synonyms for Madh9 include MADH6 and PPH2.
