Anti-JCG2 antibodies enable researchers to detect and measure the JCG2 antigen in biological samples. This target is a reported synonym of the OR8D2 gene, which encodes olfactory receptor family 8 subfamily D member 2. This protein is known to function in GPCR signaling pathways and the sensory perception of smell, among other biological roles. The human version of JCG2 has a canonical amino acid length of 311 residues and a protein mass of 34.9 kilodaltons. It is reported to be localized in the cell membrane of cells. JCG2 is a member of the G-protein coupled receptor 1 protein family.
