Anti-GPR158 antibodies are used in the immunodetection of the protein G protein-coupled receptor 158. In humans, the canonical protein has a reported length of 1215 amino acid residues and a mass of 135.5 kDa. Its subcellular localization is in the cell membrane. A member of a the G-protein coupled receptor 3 protein family, GPR158 is categorized as a type of orphan receptor. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include probable G-protein coupled receptor 158.
