OverviewNCBI Gene

This gene encodes one of the three enolase isoenzymes found in mammals. This isoenzyme is found in skeletal muscle cells in the adult where it may play a role in muscle development and regeneration. A switch from alpha enolase to beta enolase occurs in muscle tissue during development in rodents. Mutations in this gene have be associated glycogen storage disease. Alternatively spliced transcript variants encoding different isoforms have been described.[provided by RefSeq, Jul 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against ENO3 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 ENO3 as an antibody target. Whether an autoantibody or antibody against ENO3 could matter depends on whether native ENO3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

ENO3 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 ENO3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
