Anti-ATRN antibodies are used in the immunodetection of the protein attractin. In humans, the canonical protein has a reported length of 1429 amino acid residues and a mass of 158.5 kDa. Its subcellular localization is in the cell membrane and is secreted. Up to 3 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the duodenum, urinary bladder, and colon. ATRN is reported to be involved in initial immune cell clustering during inflammatory response and may regulate chemotactic activity of chemokines. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include MGCA, attractin-2, mahogany homolog, mahogany protein, and DPPT-L. ATRN gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some ATRN antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Immunofluorescence is also a common application.
