Anti-MFSD5 antibodies are used in the immunodetection of the protein major facilitator superfamily domain containing 5. In humans, the canonical protein has a reported length of 450 amino acid residues and a mass of 49.8 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. It is found to be widely expressed, but at relatively higher levels in the olfactory bulb and the skeletal muscle. A member of the Major facilitator protein superfamily, MFSD5 is known to mediate high-affinity intracellular uptake of the rare oligo-element molybdenum. Synonyms for this target antigen include major facilitator superfamily domain-containing protein 5, molybdate transporter 2 homolog, and molybdate-anion transporter. MFSD5 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. These MFSD5 antibodies are widely used in ELISA experiments, among other applications.
