Anti-LPAR3 antibodies are used in the immunodetection of the protein lysophosphatidic acid receptor 3. In humans, the canonical protein has a reported length of 353 amino acid residues and a mass of 40.1 kDa. Its subcellular localization is in the cell membrane. A member of the G-protein coupled receptor 1 protein family, LPAR3 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 Edg-7, GPCR, HOFNH30, LP-A3, LPA3, RP4-678I3, LPA receptor 3, and EDG7. LPAR3 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of LPAR3 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
