Anti-hg105 antibodies enable researchers to detect and measure the hg105 antigen in biological samples. This target is a reported synonym of the OR7D4 gene, which encodes olfactory receptor family 7 subfamily D member 4. This protein is known to function in signal transduction pathways, among other biological roles. The human version of hg105 has a canonical amino acid length of 312 residues and a protein mass of 34.4 kilodaltons. It is reported to be localized in the cell membrane of cells. hg105 is a member of the G-protein coupled receptor 1 protein family.
