Target/Biomarker information

HE4 is a protein that in humans is encoded by the WFDC2 gene HE4 is a tumor marker of ovarian cancer, with 80% sensitivity at a cut-off of 150 pmol/L.This gene encodes a protein that is a member of the 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 in many family members. This gene is expressed in pulmonary epithelial cells, and was also found to be expressed in some ovarian cancers. The encoded protein is a small secretory protein, which may be involved in sperm maturation
