The WAP four-disulfide core domain protein 2 (WFDC2), also known as epididymal protein 4, is a member of the WFDC domain family, a family of proteins that is characterized by the presence of Whey Acidic Protein (WAP) domain, and is highly expressed in the lung and salivary gland (1,2). Members of this family include SLPI and elafin, antiproteinases involved in the innate immune system (2). WFDC2 has been proposed to play a critical role in tumor formation and growth in ovarian cancer cells through the regulation of growth- and apoptosis-associated genes and may thus be a potential therapeutic target for epithelial ovarian cancer (3).
