This pathway is involved in a variety of normal ... the authors identified a number of residues in the Frizzled 8 CRD that, when mutated, disrupt Wnt binding (shown in red for one of the monomers).
Frizzled (FZD) proteins are the principal receptors of the Wnt signaling pathway. However, whether Wnt ligands induce FZD endocytosis and degradation remains elusive. The transmembrane E3 ubiquitin ...
