Anti-olfactory receptor family 1 subfamily B member 1 antibodies are used for the immunodetection of the protein encoded by the OR1B1 gene. In humans, the canonical protein has a reported length of 318 amino acid residues and a mass of 35.3 kDa. Its subcellular localization is in the cell membrane. A member of the G-protein coupled receptor 1 protein family, it is known to be involved with signal transduction pathways. Post-translational modifications have been described, including glycosylation. Other names for this target antigen include olfactory receptor 9-B, olfactory receptor OR9-26, and olfactory receptor 1B1. Gene orthologs have been identified in the rat, bovine and chimpanzee species.
