Anti-CLTRN antibodies are used in the immunodetection of the protein collectrin, amino acid transport regulator. In humans, the canonical protein has a reported length of 222 amino acid residues and a mass of 25.2 kDa. Its subcellular localization is in the cell membrane. A member of the CLTRN protein family, CLTRN is known to play an important role in amino acid transport by acting as binding partner of amino acid transporters SLC6A18 and SLC6A19, regulating their trafficking on the cell surface and their amino acid transporter activity (By similarity). Post-translational modifications have been described, including glycosylation and protein cleavage. Synonyms for this target antigen include kidney-specific membrane protein, transmembrane protein 27, and collectrin. CLTRN gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CLTRN 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.
