Anti-EPN3 antibodies are used in the immunodetection of the protein epsin 3. In humans, the canonical protein has a reported length of 632 amino acid residues and a mass of 68.2 kDa. Its subcellular localization is in the nucleus, cytoplasmic vesicles, and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably expressed in migrating keratinocytes from wounded skin, but not in differentiating keratinocytes or in normal skin. A member of the Epsin protein family, EPN3 is known to be involved with endocytosis. Synonyms for this target antigen include EPS-15-interacting protein 3. EPN3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some EPN3 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.
