Anti-phospho-Catenin, beta (Ser45)

b-catenin (92kD) is a multifunctional protein involved in cell-cell adhesion, intracellular, signaling and gene transcription. b-catenin plays a key role in the Wnt pathway which mediates numerous developmental processes. Deregulation of the Wnt pathway results in the accumulation of b-catenin in the nucleus. Stabilizing mutations of several serine/threonine residues (more frequently of serine 45) have been found in multiple tumors. Phosphorylation of b-catenin on serine 45 by casein kinase I (CKI) primes its subsequent phosphorylation of residues 33, 37 and 41 by glycogen synthase-3b (GSK-3b) and results in its degradation. Applications: Suitable for use in ELISA and Western Blotting. Other applications not tested. Recommended Dilution: Western Blotting: 1:1000-1:2000, Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
