OverviewNCBI Gene

The protein encoded by this gene interacts with components of the ubiquitin fold modifier 1 conjugation pathway and helps prevent apoptosis in ER-stressed secretory tissues. In addition, the encoded protein regulates nuclear factor-κB activity. [provided by RefSeq, Dec 2015]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against DDRGK1 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 DDRGK1 as an antibody target. Whether an autoantibody or antibody against DDRGK1 could matter depends on whether native DDRGK1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

DDRGK1 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 DDRGK1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
