Anti-olfactory receptor family 51 subfamily B member 2 antibodies are used for the immunodetection of the protein encoded by the OR51B2 gene. In humans, the canonical protein has a reported length of 312 amino acid residues and a mass of 35.4 kDa. Its subcellular localization is in the cell membrane. It is a member of the G-protein coupled receptor 1 protein family. Post-translational modifications have been described, including ubiquitination and glycosylation. Other names for this target antigen include odorant receptor HOR5'beta3, olfactory receptor 51B1, and olfactory receptor 51B2.
