Anti-MREG antibodies are used in the immunodetection of the protein melanoregulin. In humans, the canonical protein has a reported length of 214 amino acid residues and a mass of 24.9 kDa. Its subcellular localization is in the cytoplasmic vesicles, lysosomes, and cell membrane. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in photoreceptor cells. A member of the Melanoregulin protein family, MREG is suspected to be functions as cargo-recognition protein that couples cytoplasmic vesicles to the transport machinery. Post-translational modifications have been described, including palmitoylation. Synonyms for this target antigen include dilute suppressor protein homolog and whn-dependent transcript 2. MREG gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some MREG antibodies may have been used in research and have associated citations. Immunofluorescence is a widely used application for these antibodies. In addition, Western Blot is also a common application.
