Manufacturer: Cell Signaling

Size	20 µl
Reactivity	H M Mk
Sensitivity	Endogenous
Molecular Weight (kDa)	92
Source/Isotype	Rabbit
Application/Dilution	{Western Blotting: 1:1000}
Storage	Supplied in 10 mm sodium HEPES (pH 7.5), 150 mm NaCl, 100 µg/mL BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.
Specificity/Sensitivity	Phospho-β-Catenin (Thr41/Ser45) Antibody detects endogenous levels of beta-catenin only when phosphorylated at Thr41 or Ser45. This antibody does not recognize β-catenin phosphorylated at other sites.
Species Reactivity	Human, Mouse, Monkey
Source/Purification	Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr41 and Ser45 of human β-catenin. Antibodies are purified by protein A and peptide affinity chromatography.
Background	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).
