Anti-PTPN3 antibodies are used in the immunodetection of the protein protein tyrosine phosphatase non-receptor type 3. In humans, the canonical protein has a reported length of 913 amino acid residues and a mass of 104 kDa. Its subcellular localization is in the cell membrane and cytoplasm. Up to 3 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Protein-tyrosine phosphatase protein family, PTPN3 is believed to act at junctions between the membrane and the cytoskeleton. Synonyms for this target antigen include PTPH1, tyrosine-protein phosphatase non-receptor type 3, cytoskeletal-associated protein tyrosine phosphatase, protein-tyrosine phosphatase H1, and PTP-H1. PTPN3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some PTPN3 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
