OverviewNCBI Gene

The protein encoded by this gene is a pyrimidine catabolic enzyme and the initial and rate-limiting factor in the pathway of uracil and thymidine catabolism. Mutations in this gene result in dihydropyrimidine dehydrogenase deficiency, an error in pyrimidine metabolism associated with thymine-uraciluria and an increased risk of toxicity in cancer patients receiving 5-fluorouracil chemotherapy. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2009]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against DPYD can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads DPYD as an antibody target. Whether an autoantibody or antibody against DPYD could matter depends on whether native DPYD is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

DPYD is annotated as predominantly intracellular. Intracellular proteins are common autoantibody markers, becoming visible to the immune system after cell injury or altered processing, but are usually markers of disease rather than direct drivers.

Annotation status

The present source text does not explicitly label DPYD as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
