The β-catenin destruction multiprotein complex negatively regulates the canonical Wnt signalling pathway by targeting β-catenin for ubiquitination and proteasomal degradation. The complex includes axin, adenomatosis polyposis coli (APC), protein phosphatase 2A (PP2A) and glycogen synthase kinase 3 (GSK3).
