OverviewNCBI Gene

The protein encoded by this gene belongs to the complex I 19 kDa subunit family. Mammalian complex I is composed of 45 different subunits. This protein has NADH dehydrogenase activity and oxidoreductase activity. It plays an important role in transfering electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone. Alternative splicing of this gene results in multiple transcript variants encoding different isoforms.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against NDUFA8 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 NDUFA8 as an antibody target. Whether an autoantibody or antibody against NDUFA8 could matter depends on whether native NDUFA8 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

NDUFA8 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 NDUFA8 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
