OverviewNCBI Gene

This gene encodes a member of the type II transmembrane serine protease class of the trypsin superfamily. Members of this family are composed of multiple structurally distinct domains. The encoded protein converts pro-atrial natriuretic peptide to biologically active atrial natriuretic peptide, a cardiac hormone that regulates blood volume and pressure. This protein may also function as a pro-brain-type natriuretic peptide convertase. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene.

LocalizationUniProt · AlphaFold · HPA

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

CORIN is annotated at the cell surface, where native CORIN is exposed to circulating antibodies and is a prime autoantibody target that could block, deplete, or overstimulate it.

Annotation status

The present source text does not explicitly label CORIN as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
