Mouse Dickkopf-3, DKK3 ELI

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 (By similarity).
