Scientific Background: CTNNB1 is a transcription factor that acts as a downstream component of the canonical Wnt signalling pathway. In the absence of Wnt, it 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. 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. It participates in the regulation of cell adhesion, and acts as a negative regulator of centrosome cohesion. It is involved in the CDK2/PTPN6/CTNNB1/CEACAM1 pathway of insulin internalization.
