OverviewNCBI Gene

This gene encodes a member of the WAP-type four-disulfide core (WFDC) domain family. The WFDC domain, or WAP signature motif, contains eight cysteines forming four disulfide bonds at the core of the protein, and functions as a protease inhibitor. Most WFDC gene members are localized to chromosome 20q12-q13 in two clusters: centromeric and telomeric. This gene belongs to the telomeric cluster. [provided by RefSeq, Jul 2008]

LocalizationUniProt · AlphaFold · HPA

Whether an antibody against WFDC11 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 WFDC11 as an antibody target. Whether an autoantibody or antibody against WFDC11 could matter depends on whether native WFDC11 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

WFDC11 is annotated as secreted, so native WFDC11 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 WFDC11 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
