OverviewNCBI Gene

This gene encodes a complex I assembly factor protein. Complex I (NADH-ubiquinone oxidoreductase) catalyzes the transfer of electrons from NADH to ubiquinone (coenzyme Q) in the first step of the mitochondrial respiratory chain, resulting in the translocation of protons across the inner mitochondrial membrane. The encoded protein is required for assembly of complex I, and mutations in this gene are a cause of mitochondrial complex I deficiency. Alternatively spliced transcript variants have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 19. [provided by RefSeq, Dec 2011]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against NDUFAF1 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 NDUFAF1 as an antibody target. Whether an autoantibody or antibody against NDUFAF1 could matter depends on whether native NDUFAF1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

NDUFAF1 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 NDUFAF1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
