Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.

Specificity / Sensitivity

Beta-Catenin Antibody detects endogenous levels of total β-catenin protein.

Source / Purification

Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (Blue Carrier-coupled) corresponding to the carboxy-terminus 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 on Ser45. This phosphorylation event primes β-catenin for subsequent phosphorylation by GSK-3 (4-6). GSK-3β destabilizes β-catenin by phosphorylating it at Ser33, Ser37 and Thr41 (7). Mutations in these phosphorylation sites, which result in the stabilization of β-catenin protein levels, have been found in many tumor cell lines (8).
