Anti-Gastrin Releasing Peptide Receptor antibodies are used for the immunodetection of the protein encoded by the GRPR gene. In humans, the canonical protein has a reported length of 384 amino acid residues and a mass of 43.2 kDa. Its subcellular localization is in the cell membrane. It is reported to be highly expressed in the pancreas. A member of the G-protein coupled receptor 1 protein family, it is a known receptor for gastrin-releasing peptide (GRP). Post-translational modifications have been described, including glycosylation. Other names for this target antigen include BB2R, BRS2, GRP-preferring bombesin receptor, bombesin receptor 2, and BB2. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of Gastrin Releasing Peptide Receptor antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
