Figure 7. Model. Wnt5a Can Activate or Inhibit Canonical Wnt Signaling Depending on Receptor Context.
In the presence of Fz4 and LRP5, Wnt5a can activate β-catenin/TCF signaling. However, when Ror2 is expressed, Wnt5a inhibits canonical Wnt signaling downstream of β-catenin stabilization, at the level of TCF-mediated transcription.
