OverviewNCBI Gene

This gene encodes a protein that functions in the assembly of the mitochondrial ribosome by adding a pseudouridine group to 16S rRNA. Loss of this gene results in causes defects in mitochondrial protein production. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2017]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against RPUSD3 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 RPUSD3 as an antibody target. Whether an autoantibody or antibody against RPUSD3 could matter depends on whether native RPUSD3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

RPUSD3 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 RPUSD3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
