OverviewNCBI Gene
This gene encodes a member of a family of secreted proteins that function in angiogenesis. The encoded protein, which is expressed predominantly in the liver, is further processed into an N-terminal coiled-coil domain-containing chain and a C-terminal fibrinogen chain. The N-terminal chain is important for lipid metabolism, while the C-terminal chain may be involved in angiogenesis. Mutations in this gene cause familial hypobetalipoproteinemia type 2.

Whether an antibody against ANGPTL3 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 ANGPTL3 as an antibody target. Whether an autoantibody or antibody against ANGPTL3 could matter depends on whether native ANGPTL3 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
ANGPTL3 is annotated as secreted, so native ANGPTL3 circulates and is directly accessible to antibodies. Secreted and cell-surface proteins are the autoantibody targets most likely to act like drugs, blocking or depleting the native protein.
Annotation status
The present source text does not explicitly label ANGPTL3 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
