Anti-GPR31 antibodies are used in the immunodetection of the protein G protein-coupled receptor 31. In humans, the canonical protein has a reported length of 319 amino acid residues and a mass of 35.1 kDa. Its subcellular localization is in the cell membrane. A member of the G-protein coupled receptor 1 protein family, GPR31 is known to be involved with GPCR signaling pathways and the metabolism of lipids. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include HETER, HETER1, 12-(S)-hydroxy-5,8,10,14-eicosatetraenoic acid receptor, 12-(S)-HETE acid receptor, 12-(S)-HETE receptor, and 12-HETER. GPR31 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Western Blot is the most common application for the GPR31 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
