OverviewNCBI Gene
Enables actin binding activity and metallocarboxypeptidase activity. Involved in negative regulation of angiogenesis; negative regulation of blood vessel endothelial cell migration; and proteolysis. Acts upstream of or within several processes, including negative regulation of endothelial cell proliferation; negative regulation of lymphangiogenesis; and regulation of cellular senescence. Located in apical part of cell; endoplasmic reticulum; and extracellular space. Implicated in liver cirrhosis and portal hypertension. Biomarker of liver cirrhosis.

Whether an antibody against VASH1 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 VASH1 as an antibody target. Whether an autoantibody or antibody against VASH1 could matter depends on whether native VASH1 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.
VASH1 is annotated as secreted, so native VASH1 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 VASH1 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
