Anti-T2r8 antibodies enable researchers to detect and measure the T2r8 antigen in biological samples. This target is a reported synonym of the TAS2R8 gene, which encodes taste 2 receptor member 8. This protein is a known receptor that may play a role in the perception of bitterness and is gustducin-linked. The human version of T2r8 has a canonical amino acid length of 309 residues and a protein mass of 35.9 kilodaltons. It is reported to be localized in the membrane of cells. Other names for this target antigen include TRB5 and taste receptor type 2 member 8.
