  • a WIF domain, that is sufficient for Wnt binding and signaling inhibition , and WIF domain is also bound by Wnts at two sites
  • short C-terminal hydrophilic domain

  • localizes to the enamel knot in which WIF1 regulates apoptosis by mediating and regulating WNT-CTNNB1 signaling
  • basic FUNCTION
  • may be involved in mesoderm segmentation
  • antagonist of the Wnt signaling pathway, which plays a critical role in the cancer
  • role of the WIF domain as a palmitoyl binding domain required for WIF1 binding to palmitoylated Wnt and signaling inhibition
  • able to block WNT3a-mediated activation of the canonical Wnt signalling pathway
  • novel extracellular Wnt modulator in cartilage biology
  • downregulated by promoter methylation and functions as a tumor suppressor gene by inducing apoptosis in renal cell carcinoma cells
  • negative regulator of the Wnt-signaling pathway that may have important implications for tumorigenesis
  • vertebrate WIF1 blocks WNT signaling
  • is regulated by androgens and enhances androgen-dependent prostate development
  • melanocytes express WIF1 constitutively and WIF1 promotes melanogenesis in normal human melanocytes
  • WIF1 secretion by the Müllerian ducts (MDs) mesenchyme plays likely a role in MD regression in fetal males
  • regulates cancer stemness and senescence, which might have major implications in the field of cancer biology
  • plays an essential role in tooth development
    a component potential novel regulatory loop of BMP4-SMAD1-WIF1-Wnt/beta-catenin in coordinating BMP and Wnt pathways to control fetal lung development
    small molecule
  • binds to WNT proteins and inhibits their activities
  • antagonist of WNT signaling and functions by directly binding to WNT ligands in the extracellular space
  • interacting with ADIPOQ (ADIPOQ might elicit its antitumor activities at least partially through promoting WIF1 expressions)
  • interacting with MYC (MYC contributes to WIF1 transcriptional repression in a ZBTB17-dependent manner)
  • HOTAIR directly decreased WIF1 expression by promoting its histone H3K27 methylation in the promoter region and then activated the WNT/CTNNB1 signaling pathway
  • ERBB2, MYC, WIF1, RBM38, PTEN, are involved in the HOTAIR regulation network
