Anti-MRGPRF antibodies are used in the immunodetection of the protein MAS related GPR family member F. In humans, the canonical protein has a reported length of 343 amino acid residues and a mass of 38.2 kDa. Its subcellular localization is in the cell membrane. It is notably expressed in many tissues, such as the cerebral cortex, testis, and breast. A member of the G-protein coupled receptor 1 protein family, MRGPRF is categorized as a type of orphan receptor. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include G protein-coupled receptor MrgF, G-protein coupled receptor 140, G-protein coupled receptor 168, MAS-related GPR, member F, and mas-related G-protein coupled receptor member F. MRGPRF gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some MRGPRF antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
