DESCRIPTION

Also known as AMER1_HUMAN, AMER1, FAM123B, WTX. Regulator of the canonical Wnt signaling pathway. Acts by specifically binding phosphatidylinositol 4, 5-bisphosphate (PtdIns(4, 5)P2), translocating to the cell membrane and interacting with key regulators of the canonical Wnt signaling pathway, such as components of the beta-catenin destruction complex. Acts both as a positive and negative regulator of the Wnt signaling pathway, depending on the context: acts as a positive regulator by promoting LRP6 phosphorylation. Also acts as a negative regulator by acting as a scaffold protein for the beta-catenin destruction complex and promoting stabilization of Axin at the cell membrane. Promotes CTNNB1 ubiquitination and degradation. Involved in kidney development. Interacts with CTNNB1, AXIN1, LRP6, KEAP1, APC and BTRC. Interacts with SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complexes containing BTRC and/or FBXW11. Identified in the beta-catenin destruction complex containing CTNNB1, APC, AXIN1 and AXIN2. Interacts with WT1.
