Anti-GPR155 antibodies are used in the immunodetection of the protein G protein-coupled receptor 155. In humans, the canonical protein has a reported length of 870 amino acid residues and a mass of 96.9 kDa. Its subcellular localization is in the membrane. It is notably widely expressed in many tissue types. GPR155 is known to be involved with intracellular signal transduction and transmembrane transport. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include integral membrane protein GPR155 and G-protein coupled receptor PGR22. GPR155 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Immunofluorescence is the most common application for the GPR155 antibodies listed below. Western Blot, Immunocytochemistry, and Immunohistochemistry are also common applications.
