Anti-DOK3 antibodies are used in the immunodetection of the protein docking protein 3. In humans, the canonical protein has a reported length of 496 amino acid residues and a mass of 53.3 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 4 different isoforms have been reported for this protein. It is notably expressed in spleen. A member of the DOK protein family, DOK3 is known to be involved with MAPK cascade signaling pathways. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include Dok-like protein and downstream of tyrosine kinase 3. DOK3 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some DOK3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
