Anti-GPR59 antibodies enable researchers to detect and measure the GPR59 antigen in biological samples. This target is a reported synonym of the TAS2R45 gene, which encodes taste 2 receptor member 45. This protein is a known receptor that may play a role in the perception of bitterness and is gustducin-linked. The human version of GPR59 has a canonical amino acid length of 299 residues and a protein mass of 34.3 kilodaltons. It is reported to be localized in the membrane of cells. GPR59 is a member of the G-protein coupled receptor T2R protein family.
