Anti-beta Catenin (phospho Y142) antibody,Abcam,AB27798

Tyrosine phosphorylation of beta Catenin can regulate its interaction with critical components of adherens junctions. Both Fer and Fyn kinases phosphorylate tyrosine 142 in vitro and overexpression of these kinases in epithelial cells disrupts interactions between alpha and beta Catenins. The phosphorylation of tyrosine 142 may act as a switch from the adhesive to the transcriptional role of beta Catenin. Thus, site specific tyrosine phosphorylation of beta Catenin may regulate specific protein protein interactions, leading to changes in cell adhesion.

Scientific Background

Target data Key downstream component of the canonical Wnt signaling pathway (PubMed : 17524503, PubMed : 18077326, PubMed : 18086858, PubMed : 18957423, PubMed : 21262353, PubMed : 22155184, PubMed : 22647378, PubMed : 22699938). In the absence of Wnt, forms a complex with AXIN1, AXIN2, APC, CSNK1A1 and GSK3B that promotes phosphorylation on N-terminal Ser and Thr residues and ubiquitination of CTNNB1 via BTRC and its subsequent degradation by the proteasome (PubMed : 17524503, PubMed : 18077326, PubMed : 18086858, PubMed : 18957423, PubMed : 21262353, PubMed : 22155184, PubMed : 22647378, PubMed : 22699938). In the presence of Wnt ligand, CTNNB1 is not ubiquitinated and accumulates in the nucleus, where it acts as a coactivator for transcription factors of the TCF/LEF family, leading to activate Wnt responsive genes (PubMed : 17524503, PubMed : 18077326, PubMed : 18086858, PubMed : 18957423, PubMed : 21262353, PubMed : 22155184, PubMed : 22647378, PubMed : 22699938). Involved in the regulation of cell adhesion, as component of an E-cadherin : catenin adhesion complex (By similarity). Acts as a negative regulator of centrosome cohesion (PubMed : 18086858). Involved in the CDK2/PTPN6/CTNNB1/CEACAM1 pathway of insulin internalization (PubMed : 21262353). Blocks anoikis of malignant kidney and intestinal epithelial cells and promotes their anchorage-independent growth by down-regulating DAPK2 (PubMed : 18957423). Disrupts PML function and PML-NB formation by inhibiting RANBP2-mediated sumoylation of PML (PubMed : 22155184). Promotes neurogenesis by maintaining sympathetic neuroblasts within the cell cycle (By similarity). Involved in chondrocyte differentiation via interaction with SOX9 : SOX9-binding competes with the binding sites of TCF/LEF within CTNNB1, thereby inhibiting the Wnt signaling (By similarity). Acts as a positive regulator of odontoblast differentiation during mesenchymal tooth germ formation, via promoting the transcription of differentiation factors such as LEF1, BMP2 and BMP4 (By similarity). Activity is repressed in a MSX1-mediated manner at the bell stage of mesenchymal tooth germ formation which prevents premature differentiation of odontoblasts (By similarity).
