OverviewNCBI Gene
This gene encodes a mitochondrial protein that belongs to the 2-oxoacid dehydrogenase family. This protein is one of the three components (the E2 component) of the 2-oxoglutarate dehydrogenase complex that catalyzes the overall conversion of 2-oxoglutarate to succinyl-CoA and CO(2). Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Oct 2011]

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