OverviewNCBI Gene

The protein encoded by this gene is an enzyme that synthesizes the prenyl side-chain of coenzyme Q, or ubiquinone, one of the key elements in the respiratory chain. The gene product catalyzes the formation of all trans-polyprenyl pyrophosphates from isopentyl diphosphate in the assembly of polyisoprenoid side chains, the first step in coenzyme Q biosynthesis. Defects in this gene are a cause of coenzyme Q10 deficiency.[provided by RefSeq, Oct 2009]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against PDSS2 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 PDSS2 as an antibody target. Whether an autoantibody or antibody against PDSS2 could matter depends on whether native PDSS2 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

PDSS2 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 PDSS2 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
