  • Target

    • Function

      Involved in pyrimidine base degradation. Catalyzes the reduction of uracil and thymine. Also involved the degradation of the chemotherapeutic drug 5-fluorouracil.
    • Tissue specificity

      Found in most tissues with greatest activity found in liver and peripheral blood mononuclear cells.
    • Pathway

      Amino-acid biosynthesis; beta-alanine biosynthesis.
    • Involvement in disease

      Defects in DPYD are the cause of dihydropyrimidine dehydrogenase deficiency (DPYD deficiency) [MIM:274270]; also known as hereditary thymine-uraciluria or familial pyrimidinemia. DPYD deficiency is a disease characterized by persistent urinary excretion of excessive amounts of uracil, thymine and 5-hydroxymethyluracil. Patients suffering from this disease show a severe reaction to the anticancer drug 5-fluorouracil. This reaction includes stomatitis, Leukopenia, thrombocytopenia, hair loss, diarrhea, fever, marked weight loss, cerebellar ataxia, and neurologic symptoms, progressing to semicoma.
    • Sequence similarities

      Belongs to the dihydropyrimidine dehydrogenase family.
      Contains 3 4Fe-4S ferredoxin-type domains.

    • Immunocytochemistry/Immunofluorescence analysis Jurkat (human acute T cell leukaemia) cells labelling DPD with purified ab134922 at a dilution of 1/500. Cells were fixed with 100% methanol. An Alexa Fluor® 488-conjugated goat anti-rabbit IgG (ab150077) at dilution of 1/1000 was used as the secondary antibody. Nuclei counterstained with DAPI (blue).

      Secondary Only Control: PBS was used instead of the primary antibody as the negative control.
