OverviewNCBI Gene

This gene encodes a protein that transfers phenylalanine to its cognate tRNA. This protein localizes to the mitochondrion and plays a role in mitochondrial protein translation. Mutations in this gene can cause combined oxidative phosphorylation deficiency 14 (Alpers encephalopathy). Alternative splicing results in multiple transcript variants.

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against FARS2 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 FARS2 as an antibody target. Whether an autoantibody or antibody against FARS2 could matter depends on whether native FARS2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

FARS2 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 FARS2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
