Anti-TRAK2 antibodies are used in the immunodetection of the protein trafficking kinesin protein 2. In humans, the canonical protein has a reported length of 914 amino acid residues and a mass of 101.4 kDa. Its subcellular localization is in the mitochondria and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is found to be widely expressed, with highest expression in the heart. A member of the Milton protein family, TRAK2 is believed to regulate endosome-to-lysosome trafficking of membrane cargo, including EGFR. Synonyms for this target antigen include O-linked N-acetylglucosamine transferase interacting protein 98, amyotrophic lateral sclerosis 2 (juvenile) chromosome region, candidate 3, and trafficking kinesin-binding protein 2. TRAK2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of TRAK2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
