Anti-GRAMD1B antibodies are used in the immunodetection of the protein GRAM domain containing 1B. In humans, the canonical protein has a reported length of 738 amino acid residues and a mass of 85.4 kDa. Its subcellular localization is in the ER and cell membrane. Up to 4 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. GRAMD1B 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 GRAM domain-containing protein 1B, long intergenic non-protein coding RNA 1059, and protein Aster-B. GRAMD1B gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some Gramd1b antibodies may have been used in research and have associated citations. ELISA is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
