Anti-OR8U3 antibodies are used in the immunodetection of the protein olfactory receptor family 8 subfamily U member 3. In humans, the canonical protein has a reported length of 324 amino acid residues and a mass of 36.7 kDa. Its subcellular localization is in the cell membrane. A member of the G-protein coupled receptor 1 protein family, OR8U3 is known to be involved with GPCR signaling pathways and the sensory perception of smell. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include olfactory receptor 5R1, olfactory receptor OR11-185, olfactory receptor family 5 subfamily R member 1, olfactory receptor, family 5, subfamily R, member 1 pseudogene, and olfactory receptor 8U3. OR8U3 gene orthologs have been reported in the mouse, rat and bovine species.
