Wnt signalling: antagonistic Dickkopfs.
Dickkopf proteins are secreted antagonists of the Wnt cell signalling molecules, which have a novel mode of action. Dickkopf1 binds to the LRP5/6 Wnt co-receptor and prevents the formation of active Wnt--Frizzled--LRP5/6 receptor complexes, thus blocking the canonical Wnt--beta-catenin pathway.
