OverviewNCBI Gene

The protein encoded by this gene is an omega class glutathione S-transferase (GST). GSTs are involved in the metabolism of xenobiotics and carcinogens. Four transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Jul 2010]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against GSTO2 can act on the native protein depends on physical access: surface and secreted proteins are reachable by circulating antibodies, intracellular proteins usually are not.

Genetic constraint and essentialitygnomAD · DepMap

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads GSTO2 as an antibody target. Whether an autoantibody or antibody against GSTO2 could matter depends on whether native GSTO2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

GSTO2 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 GSTO2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
