OverviewNCBI Gene

UCRC is a subunit of mitochondrial complex III (ubiquinol-cytochrome c reductase; EC 1.10.2.2), which forms the middle segment of the respiratory chain of the inner mitochondrial membrane (Schagger et al., 1995 [PubMed 8592474]).[supplied by OMIM, Mar 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against UQCR10 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

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 UQCR10 as an antibody target. Whether an autoantibody or antibody against UQCR10 could matter depends on whether native UQCR10 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

UQCR10 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 UQCR10 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
