OverviewNCBI Gene
The protein encoded by this gene is an enzyme that catalyzes the first step in the dolichol-linked oligosaccharide pathway for glycoprotein biosynthesis. This enzyme belongs to the glycosyltransferase family 4. This protein is an integral membrane protein of the endoplasmic reticulum. The congenital disorder of glycosylation type Ij is caused by mutation in the gene encoding this enzyme. [provided by RefSeq, Jul 2008]

Whether an antibody against DPAGT1 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 DPAGT1 as an antibody target. Whether an autoantibody or antibody against DPAGT1 could matter depends on whether native DPAGT1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
DPAGT1 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 DPAGT1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
