Anti-dermatopontin antibodies are used in the immunodetection of the protein encoded by the DPT gene. In humans, the canonical protein has a reported length of 201 amino acid residues and a mass of 24 kDa. Its subcellular localization is in the extracellular matrix and is also secreted. It is reported to be expressed in fibroblasts, heart, skeletal muscle, brain and pancreas. A member of the Dermatopontin protein family, it is known to be involved with cell adhesion and the regulation of cell proliferation. Post-translational modifications have been described, including sulfation. Other names for this target antigen include TRAMP and tyrosine-rich acidic matrix protein.
