Anti-olfactory receptor family 4 subfamily C member 16 antibodies are used for the immunodetection of the protein encoded by the OR4C16 gene. In humans, the canonical protein has a reported length of 310 amino acid residues and a mass of 35 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 glycosylation. Other names for this target antigen include olfactory receptor 4C16 and olfactory receptor OR11-135.
