Anti-GPR173 antibodies are used in the immunodetection of the protein G protein-coupled receptor 173. In humans, the canonical protein has a reported length of 373 amino acid residues and a mass of 41.5 kDa. Its subcellular localization is in the cell membrane. It is reported to be expressed in the ovary, specifically in granulosa cells of follicles that have passed the primary stage and in oocytes. A member of the G-protein coupled receptor 1 protein family, GPR173 is known to be involved with signal transduction pathways. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include probable G-protein coupled receptor 173, super conserved receptor expressed in brain 3, and SREB3. GPR173 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. Some GPR173 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
