New work from Wikramanayake & Martindale Labs suggests ancestral β-catenin-binding motif-like sequence in Axin-RGS acquired weak β-catenin-binding capacity in early-emerging metazoans.... In bilaterians, a duplicated motif evolved higher-affinity for β-catenin, while the ancestral sequence was lost.

Reconstructing the evolutionary origin of β-catenin recognition in the Wnt destruction complex
Abstract. Emergence of Wnt/β-catenin signaling was a major metazoan innovation, yet how its core molecular interactions evolved remains unresolved. Here, w
