Anti-CYSLTR2 antibodies are used in the immunodetection of the protein cysteinyl leukotriene receptor 2. In humans, the canonical protein has a reported length of 346 amino acid residues and a mass of 39.6 kDa. Its subcellular localization is in the cell membrane. It is found to be widely expressed, with highest levels in the heart, placenta, spleen, peripheral blood leukocytes and adrenal gland. A member of the G-protein coupled receptor 1 protein family, CYSLTR2 is a known receptor for cysteinyl leukotrienes. Post-translational modifications have been described, including glycosylation. CYSLTR2 is also used as a cellular marker for characterizing granulocytes. Synonyms for this target antigen include G-protein coupled receptor HG57, cysteinyl leukotriene CysLT2 receptor, and G-protein coupled receptor GPCR21. CYSLTR2 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some CYSLTR2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
