OverviewNCBI Gene

This gene encodes a member of the WAP-type four-disulfide core (WFDC) domain family. Most WFDC proteins contain only one WFDC domain, and this encoded protein contains two WFDC domains. 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 centromeric cluster. [provided by RefSeq, Jul 2008]

Does the body need this protein intact? Low LOEUF or a strong DepMap dependency means loss or blockade of the protein is likely to be felt.

Antibody and autoantibody relevanceSeroatlas analysis

Seroatlas reads WFDC5 as an antibody target. Whether an autoantibody or antibody against WFDC5 could matter depends on whether native WFDC5 is physically reachable, whether the body needs it intact, and whether it acts in a disease-relevant tissue.

WFDC5 is annotated as secreted, so native WFDC5 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 WFDC5 as an autoantigen. Seroatlas presents hypothesis context only and does not manufacture a known-serology claim.
