Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting
Species predicted to react based on 100% sequence homology: Mouse, Rat, Dog, Pig.
Specificity / Sensitivity
Phospho-β-Catenin (Ser45) Antibody detects endogenous levels of beta-catenin only when phosphorylated at serine 45. It does not recognize β-catenin phosphorylated at other sites.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser45 of human β-catenin. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from HEK293 cells untreated and treated with calyculin A (50 nM for 30 minutes), using Phospho-β-Catenin (upper) and β-Catenin Antibody #9562 (lower).
Western blot analysis of extracts from HEK293 cells untreated and treated with 50 nM calyculin A for 30 minutes, using Phospho-β-Catenin (Ser45) Antibody (lanes 1-2) or the same antibody after preincubation with listed peptides (lanes 3-8). (S45-P is phospho-Ser45 peptide; S33/37/T41-P is phospho-Ser33/37/Thr41 peptide; S45-non-P is nonphospho-Ser45 peptide.)

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).
