    motifs/domains
  • a signal peptide followed by an acidic and cysteine rich polypeptide
  • two WAP domains, WAP domains playing pivotal roles in the antimicrobial and/or antiprotease activities and their application in therapeutics are expected to have practical value
  • a conserved motif, containing eight cysteines
    • conjugated GlycoP

    basic FUNCTION
  • potentially involved in sperm maturation
  • a putative serum tumour marker for ovarian cancer
  • may be a component of the innate immune defences of the lung, nasal and oral cavities
  • functions in concert with related WAP domain containing proteins in epithelial host defence
  • its expression is associated with cancer cell adhesion, migration and tumor growth, which can be related to its effects on the EGFR-MAPK signaling pathway
  • participates in the process of ovarian cancer cell maturation and is responsible for engaging the progression of the ovarian cancer

    Marker
  • its expression is associated with lymph node involvement and is a possible predictive factor of breast cancer recurrence
  • measuring WFDC2 in urine may aid diagnosis and the monitoring of response to therapy, in ovarian carcinoma
  • may be a screening tool for early diagnosis of TCC in the urinary system, and may become a prognostic marker for TCC in the urinary system
  • novel and specific biomarker for epithelial ovarian cancer (EOC)
