OverviewNCBI Gene
Glutamic-oxaloacetic transaminase is a pyridoxal phosphate-dependent enzyme which exists in cytoplasmic and mitochondrial forms, GOT1 and GOT2, respectively. GOT plays a role in amino acid metabolism and the urea and tricarboxylic acid cycles. The two enzymes are homodimeric and show close homology. [provided by RefSeq, Jul 2008]

Whether an antibody against GOT1 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 GOT1 as an antibody target. Whether an autoantibody or antibody against GOT1 could matter depends on whether native GOT1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
GOT1 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 GOT1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
