Recombinant Non-Phospho (Active) β-Catenin (Ser33, Ser37, Thr41) Monoclonal Antibody

β-catenin is a key downstream effector in the Wnt signaling pathway. It is implicated in two major biological processes in vertebrates: early embryonic development and tumorigenesis. CK1 phosphorylates β-catenin at Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3β. GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37, and Thr41. Mutations at these sites result in the stabilization of β-catenin protein levels and have been found in many tumor cell lines.Non-phospho (Active) β-Catenin (Ser33/37/Thr41) Rabbit mAb specifically recognizes β-catenin that is non-phosphorylated at Ser33, Ser33 or Thr41. Non-phospho β-Catenin (Ser33, Ser33 or Thr41) protein is useful as a readout of stabilized β-catenin protein, and therefore functionally active in cell-cell adhesion and mediating transcriptional activity via the canonical Wnt signaling pathway.
