OverviewNCBI Gene

Enables proton channel activity. Contributes to proton-transporting ATP synthase activity, rotational mechanism. Involved in proton motive force-driven mitochondrial ATP synthesis and proton transmembrane transport. Located in mitochondrion. Part of proton-transporting ATP synthase complex. Implicated in Leber hereditary optic neuropathy; NARP syndrome; Parkinson's disease; multiple sclerosis; and systemic lupus erythematosus. [provided by Alliance of Genome Resources, Jul 2025]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against MT-ATP6 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 MT-ATP6 as an antibody target. Whether an autoantibody or antibody against MT-ATP6 could matter depends on whether native MT-ATP6 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

MT-ATP6 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 MT-ATP6 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
