Anti-OR19-5 antibodies enable researchers to detect and measure the OR19-5 antigen in biological samples. This target is a reported synonym of the OR7C1 gene, which encodes olfactory receptor family 7 subfamily C member 1. This protein is known to function in signal transduction pathways and spermatogenesis, among other biological roles. The human version of OR19-5 has a canonical amino acid length of 320 residues and a protein mass of 35.5 kilodaltons. It is reported to be localized in the cell membrane of cells. OR19-5 is a member of the G-protein coupled receptor 1 protein family.
