Anti-SLC66A3 antibodies are used in the immunodetection of the protein solute carrier family 66 member 3. In humans, the canonical protein has a reported length of 202 amino acid residues and a mass of 22.6 kDa. Its subcellular localization is in the membrane. Up to 2 different isoforms have been reported for this protein. Synonyms for this target antigen include PQ loop repeat containing 3 and PQ-loop repeat-containing protein 3. SLC66A3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
