Anti-LPAR4 antibodies are used in the immunodetection of the protein lysophosphatidic acid receptor 4. In humans, the canonical protein has a reported length of 370 amino acid residues and a mass of 41.9 kDa. Its subcellular localization is in the cell membrane. It is reported to be highly expressed in ovary. A member of the G-protein coupled receptor 1 protein family, LPAR4 is a known receptor for lysophosphatidic acid (LPA), a mediator of diverse cellular activities. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include LPA4, P2RY9, P2Y5-LIKE, P2Y9, G-protein coupled receptor 23, LPA receptor 4, LPA-4, and GPR23. LPAR4 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some LPAR4 antibodies may have been used in research and have associated citations. Immunohistochemistry is a widely used application for these antibodies. In addition, Western Blot is also a common application.
