An aggregon in conductin/axin2 regulates Wnt/β-catenin signaling and holds potential for cancer therapy

Abstract

Polymerization of axin proteins is essential to suppress Wnt/β-catenin signaling. Here, the authors identify an aggregation site in the conductin/axin2 RGS domain that prevents its polymerization and show that a short peptide masking this aggregon promotes polymerization of conductin/axin2, downregulation of Wnt pathway activity and growth inhibition of colorectal cancer cells.
