OverviewNCBI Gene
The protein encoded by this gene is a peroxisomal thioesterase that appears to be involved more in the oxidation of fatty acids rather than in their formation. The encoded protein can bind to the human immunodeficiency virus-1 protein Nef, and mediate Nef-induced down-regulation of CD4 in T-cells. [provided by RefSeq, Oct 2010]

Antibody and autoantibody relevanceSeroatlas analysis
Seroatlas reads ACOT8 as an antibody target. Whether an autoantibody or antibody against ACOT8 could matter depends on whether native ACOT8 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
ACOT8 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 ACOT8 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
