Anti-DTD antibodies enable researchers to detect and measure the DTD antigen in biological samples. This target is a reported synonym of the SLC26A2 gene, which encodes solute carrier family 26 member 2. This protein is known to function in chondrocyte differentiation, among other biological roles. The human version of DTD has a canonical amino acid length of 739 residues and a protein mass of 81.7 kilodaltons. It is reported to be localized in the cell membrane of cells and notably expressed in the parathyroid gland, endometrium, colon, appendix, and adrenal gland. DTD is a member of the SLC26A/SulP transporter (TC 2.A.53) protein family.
