OverviewNCBI Gene

This gene encodes a protein that may function in the control of cell pluripotency and early embryogenesis. Expression of this gene is a specific marker for pluripotent stem cells. Pseudogenes of this gene are located on the short arm of chromosome 10 and the long arm of chromosomes 14 and 19. [provided by RefSeq, Dec 2010]

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads DPPA5 as an antibody target. Whether an autoantibody or antibody against DPPA5 could matter depends on whether native DPPA5 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

DPPA5 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 DPPA5 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
