Anti-Thymidine Phosphorylase antibodies are used in the immunodetection of the protein encoded by the TYMP gene. In humans, the canonical protein has a reported length of 482 amino acid residues and a mass of 50 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Thymidine/pyrimidine-nucleoside phosphorylase protein family, it is suspected to have a role in maintaining the integrity of the blood vessels. Other names for this target antigen include ECGF1, MEDPS1, MNGIE, MTDPS1, PDECGF, TP, hPD-ECGF, and ECGF.
