Anti-OR2K1 antibodies enable researchers to detect and measure the OR2K1 antigen in biological samples. This target is a reported synonym of the OR13C4 gene, which encodes olfactory receptor family 13 subfamily C member 4. The human version of OR2K1 has a canonical amino acid length of 318 residues and a protein mass of 35.6 kilodaltons. It is reported to be localized in the cell membrane of cells. OR2K1 is a member of the G-protein coupled receptor 1 protein family.
