Anti-TRB3 antibodies enable researchers to detect and measure the TRB3 antigen in biological samples. This target is a reported synonym of the TAS2R13 gene, which encodes taste 2 receptor member 13. This protein is known to function in cell division, among other biological roles. The human version of TRB3 has a canonical amino acid length of 303 residues and a protein mass of 35.1 kilodaltons. It is reported to be localized in the membrane of cells. TRB3 is a member of the G-protein coupled receptor T2R protein family.
