OverviewNCBI Gene
The protein encoded by this gene is a peptidyl-tRNA hydrolase and a vital component of the large mitochondrial ribosome. The encoded protein serves as a ribosome release factor for this ribosome, which translates mitochondrial genes. This protein may be responsible for degrading prematurely-terminated polypeptides and for reusing stalled ribosomes. Two transcript variants encoding different isoforms have been found for this gene.

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads MRPL58 as an antibody target. Whether an autoantibody or antibody against MRPL58 could matter depends on whether native MRPL58 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
MRPL58 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 MRPL58 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
