OverviewNCBI Gene

Inner mitochondrial membrane complex III (CIII) is the main enzyme complex in the mitochondrial respiratory chain, and Rieske Fe-S protein (UQCRFS1) is the last catalytic subunit added to the complex. The protein encoded by this gene is a nuclear-encoded mitochondrial matrix protein that stabilizes UQCRFS1 and chaperones it to the CIII complex. Defects in this gene are a cause of mitochondrial complex III deficiency, nuclear type 8. Three transcript variants encoding two different isoforms have been found for this gene.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against LYRM7 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 LYRM7 as an antibody target. Whether an autoantibody or antibody against LYRM7 could matter depends on whether native LYRM7 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

LYRM7 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 LYRM7 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
