OverviewNCBI Gene

Epoxide hydrolase is a critical biotransformation enzyme that converts epoxides from the degradation of aromatic compounds to trans-dihydrodiols which can be conjugated and excreted from the body. Epoxide hydrolase functions in both the activation and detoxification of epoxides. Mutations in this gene cause preeclampsia, epoxide hydrolase deficiency or increased epoxide hydrolase activity. Alternatively spliced transcript variants encoding the same protein have been found for this gene.[provided by RefSeq, Dec 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against EPHX1 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 EPHX1 as an antibody target. Whether an autoantibody or antibody against EPHX1 could matter depends on whether native EPHX1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

EPHX1 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 EPHX1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
