Structures of Wnt-antagonist ZNRF3 and its complex with R-spondin 1 and implications for signaling.

Structures of Wnt-antagonist ZNRF3 and its complex with R-spondin 1 and implications for signaling.

Zinc RING finger 3 (ZNRF3) and its homolog RING finger 43 (RNF43) antagonize Wnt signaling in adult stem cells by ubiquitinating Frizzled receptors (FZD), which leads to endocytosis of the Wnt receptor. Conversely, binding of ZNRF3/RNF43 to LGR4-6 - R-spondin blocks Frizzled ubiquitination and enhan...
