Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 60 kDa (predicted molecular weight: 38 kDa).
ICC/IF 1/100.
IP 1/50 - 1/70.


  • Function
    Antagonizes canonical Wnt signaling by inhibiting LRP5/6 interaction with Wnt and by forming a ternary complex with the transmembrane protein KREMEN that promotes internalization of LRP5/6. DKKs play an important role in vertebrate development, where they locally inhibit Wnt regulated processes such as antero-posterior axial patterning, limb development, somitogenesis and eye formation. In the adult, Dkks are implicated in bone formation and bone disease, cancer and Alzheimer disease.
  • Tissue specificity
    Highest expression in heart, brain, and spinal cord.
  • Sequence similarities
    Belongs to the dickkopf family.
  • Domain
    The C-terminal cysteine-rich domain mediates interaction with LRP5 and LRP6.
  • Post-translational
    N- and O-glycosylated.
  • Cellular localization
