Anti-KiSS1 receptor antibodies are used in the immunodetection of the protein encoded by the KISS1R gene. In humans, the canonical protein has a reported length of 398 amino acid residues and a mass of 42.6 kDa. Its subcellular localization is in the cell membrane. A member of the G-protein coupled receptor 1 protein family, it is a known receptor for metastin (kisspeptin-54 or kp-54), a C-terminally amidated peptide of KiSS1. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include G-protein coupled receptor OT7T175, hypogonadotropin-1, kisspeptins receptor, metastin receptor, and G protein-coupled receptor 54.
