OverviewNCBI Gene
This gene encodes a protein which is part of mitochondrial complex 1, part of the oxidative phosphorylation system in mitochondria. Complex 1 transfers electrons to ubiquinone from NADH which establishes a proton gradient for the generation of ATP. Mutations in this gene are associated with Leigh syndrome due to mitochondrial complex 1 deficiency. Pseudogenes of this gene are located on chromosomes 5 and 13. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2012]

Whether an antibody against NDUFA12 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 NDUFA12 as an antibody target. Whether an autoantibody or antibody against NDUFA12 could matter depends on whether native NDUFA12 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
NDUFA12 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 NDUFA12 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
