Background Information

Beta Catenin/β-catenin, also known as CTNNB1, is a key downstream component of the canonical Wnt pathway that plays diverse and critical roles in embryonic development and adult tissue homeostasis. The N-terminal (1-49 amino acids) of β-catenin is the key region for its stability and the degradation by ubiquitin-proteasome system, and phosphorylation of β-catenin at the N-terminal Ser33, Ser37, Thr41, and Ser45 promotes its ubiquitination and degradation (PMID: 31930681). Phosphorylated β-catenin is targeted for ubiquitination-dependent proteolysis.
