β-Catenin Antibody
β-catenin is a key downstream effector in the Wnt signaling pathway (1). It is implicated in two major biological processes in vertebrates: early embryonic development (2) and tumorigenesis (3). CK1 phosphorylates β-catenin at Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3β (4-6). GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37, and Thr41 (7). Mutations at these sites result in the stabilization of β-catenin protein levels and have been found in many tumor cell lines (8).
Both Akt and PKA were shown to phosphorylate β-catenin at Ser552 and Ser675. Phosphorylation at Ser552 and Ser675 induces β-catenin accumulation in the nucleus and increases its transcriptional activity (9-12).
The dual role of b-catenin in Wnt signaling and in cell–cell adhesion.
