OverviewNCBI Gene
This gene encodes an arginyltransferase, an enzyme that is involved in posttranslational conjugation of arginine to N-terminal aspartate or glutamate residues. Conjugation of arginine to the N-terminal aspartate or glutamate targets proteins for ubiquitin-dependent degradation. Alternative splicing results in multiple transcript variants.

Whether an antibody against ATE1 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 ATE1 as an antibody target. Whether an autoantibody or antibody against ATE1 could matter depends on whether native ATE1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
ATE1 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 ATE1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
