Anti-RETSAT antibodies are used in the immunodetection of the protein retinol saturase. In humans, the canonical protein has a reported length of 610 amino acid residues and a mass of 66.8 kDa. Its subcellular localization is in the ER. Up to 2 different isoforms have been reported for this protein. It is reported to be expressed in the liver; expression positively correlates with obesity and liver steatosis. A member of the Carotenoid/retinoid oxidoreductase protein family, RETSAT is known to catalyze the saturation of all-trans-retinol to all-trans-13,14-dihydroretinol. Synonyms for this target antigen include PPAR-alpha-regulated and starvation-induced gene protein, all-trans-13,14-dihydroretinol saturase, and all-trans-retinol 13,14-reductase. RETSAT gene orthologs have been reported in the mouse, rat, bovine, frog and chicken species. Some RETSAT antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
