Background
β-catenin (Catenin beta-1) belongs to the cadherin-associated protein family and exerts dual functions in cell-cell adhesion and Wnt signal transduction. As a component of cell adhesion complex, it localizes beneath plasma membrane and bridges E-cadherin to cytoskeleton to preserve epithelial tissue architecture. It also serves as the central effector of Wnt signaling. In the absence of Wnt ligands, β-catenin is recognized by destruction complex and phosphorylated at Ser37, which triggers ubiquitin-proteasome-dependent degradation and keeps its cellular abundance low. Upon Wnt activation, Ser37 phosphorylation is suppressed, allowing β-catenin translocation into nucleus to interact with TCF/LEF transcription factors, modulating cell proliferation, differentiation, apoptosis and oncogenesis. Phosphorylation at Ser37 is a hallmark for β-catenin primed for degradation, widely applied in oncology and developmental biology research.
