Measured by its ability to inhibit Wnt induced TCF reporter activity in HEK293 human embryonic kidney cells. Recombinant Human Dkk-4 inhibits a constant dose of 500 ng/mL of Recombinant Human Wnt-3a. The ED50 for this effect is 150-900 ng/mL.
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).
Post-translational: Appears to be not glycosylated.Can be proteolytically processed by a furin-like protease.

Recombinant Human Dkk-4 Protein (rp167607) - SDS-PAGE
2 μg/lane of Recombinant Human Dkk-4 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 35 kDa under reducing conditions and 25 & 35 kDa under non-reducing conditions due to glycosylation.
