OverviewNCBI Gene

Mitochondrial ATP synthase catalyzes ATP synthesis, utilizing an electrochemical gradient of protons across the inner membrane during oxidative phosphorylation. It is composed of two linked multi-subunit complexes: the soluble catalytic core, F1, and the membrane-spanning component, Fo, which comprises the proton channel. The F1 complex consists of 5 different subunits (alpha, beta, gamma, delta, and epsilon) assembled in a ratio of 3 alpha, 3 beta, and a single representative of the other 3. The Fo seems to have nine subunits (a, b, c, d, e, f, g, F6 and 8). This gene encodes the g subunit of the Fo complex. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Jun 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against ATP5MG can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads ATP5MG as an antibody target. Whether an autoantibody or antibody against ATP5MG could matter depends on whether native ATP5MG is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

ATP5MG 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 ATP5MG as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
