OverviewNCBI Gene
The protein encoded by this gene is similar in sequence to histidyl-tRNA synthetase, which hydrolyzes D-tyrosyl-tRNA(Tyr) into D-tyrosine and free tRNA(Tyr). The encoded protein binds the DNA unwinding element and plays a role in the initiation of DNA replication. Alternative splicing results in multiple transcript variants encoding different isoforms.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads DTD1 as an antibody target. Whether an autoantibody or antibody against DTD1 could matter depends on whether native DTD1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
DTD1 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 DTD1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
