WebJun 1, 2024 · Beta-catenin, encoded by the CTNNB1 gene, is important for cell adhesion and is mainly present in the cell membranes [1]. Beta-catenin also plays an important role in a signaling pathway of progenitor cell proliferation and differentiation. Mutations of CTNNB1 are oncogenic in several tumor types [ 1 ]. WebFeb 20, 2004 · As a result, β-catenin accumulates in the cytoplasm, and presumably, this leads to translocation of this protein into the nucleus where it interacts with the DNA-binding T-cell factor complex and acts as a transcriptional activator, thus turning on target genes, including c- myc and cyclin D1 in the case of colorectal cancer (9, 10). WebBeta-catenin is involved in cellular cohesion through binding to the cytoplasmic tail of E-cadherin, and in intracellular signaling as a component of the Wnt pathway. In normal cells, B-catenin levels are regulated by the adenomatous polyposis coli (APC) protein, which promotes normal degradation of the protein. portland cement invented
