OverviewNCBI Gene

The protein encoded by this gene is localized to the mitochondrion and acts as a homohexamer to recycle glutamate during neurotransmission. The encoded enzyme catalyzes the reversible oxidative deamination of glutamate to alpha-ketoglutarate. This gene is intronless.[provided by RefSeq, Jan 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against GLUD2 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 GLUD2 as an antibody target. Whether an autoantibody or antibody against GLUD2 could matter depends on whether native GLUD2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

GLUD2 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 GLUD2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
