OverviewNCBI Gene

This gene encodes a protein that is related to epidermal growth factor receptor pathway substrate 8 (EPS8), a substrate for the epidermal growth factor receptor. The function of this protein is unknown. Alternatively spliced transcript variants encoding different isoforms exist. [provided by RefSeq, Jul 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against EPS8L3 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 EPS8L3 as an antibody target. Whether an autoantibody or antibody against EPS8L3 could matter depends on whether native EPS8L3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

EPS8L3 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 EPS8L3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
