Anti-GRAMD1A antibodies are used in the immunodetection of the protein GRAM domain containing 1A. In humans, the canonical protein has a reported length of 724 amino acid residues and a mass of 80.7 kDa. Its subcellular localization is in the cytoplasmic vesicles, ER, and cell membrane. Up to 3 different isoforms have been reported for this protein. It is notably expressed in the liver. GRAMD1A is reported to be a cholesterol transporter that mediates non-vesicular transport of cholesterol from the plasma membrane (PM) to the endoplasmic reticulum (ER) (By similarity). Synonyms for this target antigen include protein Aster-A and GRAM domain-containing protein 1A. GRAMD1A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Some GRAMD1A antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
