Anti-GPR33 antibodies are used in the immunodetection of the protein G protein-coupled receptor 33. In humans, the canonical protein has a reported length of 333 amino acid residues and a mass of 38.2 kDa. Its subcellular localization is in the cell membrane. It is reported to be expressed in spleen, lung, heart, liver, kidney, pancreas, thymus, gonads and leukocytes. A member of the G-protein coupled receptor 1 protein family, GPR33 is known to be involved with inflammatory response pathways and the regulation of intracellular calcium. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include probable G-protein coupled receptor 33 and G protein-coupled receptor 33 pseudogene. GPR33 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is the most common application for the Gpr33 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
