Anti-GPR156 antibodies are used in the immunodetection of the protein G protein-coupled receptor 156. In humans, the canonical protein has a reported length of 814 amino acid residues and a mass of 89.1 kDa. Its subcellular localization is in the cell membrane. Up to 2 different isoforms have been reported for this protein. A member of the G-protein coupled receptor 3 protein family, GPR156 is categorized as a type of orphan receptor. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include G protein-coupled receptor PGR28, GABAB-related G-protein coupled receptor, and probable G-protein coupled receptor 156. GPR156 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some GPR156 antibodies may have been used in research and have associated citations. Immunofluorescence is a widely used application for these antibodies. ELISA, Western Blot, and Immunocytochemistry are also common applications.
