Species predicted to react based on 100% sequence homology: Chicken, Xenopus, Zebrafish, Bovine, Dog, Pig.
Specificity / Sensitivity
Phospho-β-Catenin (Ser33/37/Thr41) Antibody detects endogenous levels of β-catenin only when phosphorylated at serines 33, 37 or threonine 41. It does not recognize beta-catenin phosphorylated at other sites.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser33, Ser37 and Thr41 of human β-catenin. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from 293 cells, pretreated with 20 mM LiCl for 30 minutes and then with 50 nM calyculin A, using Phospho-β-Catenin (Ser33/37/Thr41) Antibody (upper) or β-Catenin Antibody #9562 (lower).
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).
