Biolegend, 844605, PE anti-β Catenin 1 (CTNNB1) Antibody, 25tests

β-catenin is part of a complex of proteins that constitute adherens junctions (AJs). AJs are necessary for the creation and maintenance of epithelial cell layers by regulating cell growth and adhesion between cells. The encoded protein also anchors the actin cytoskeleton and may be responsible for transmitting the contact inhibition signal that causes cells to stop dividing once the epithelial sheet is complete. β-catenin also plays a key role in Wnt signaling pathways and thus is involved in neural differentiation, synaptic plasticity, neurodegenerative disease, and prevention of apoptosis. Finally, this protein binds to the product of the adenomatous polyposis coli (APC) gene, which is mutated in the adenomatous polyposis of the colon. Mutations in this gene are a cause of colorectal cancer (CRC), pilomatrixoma (PTR), medulloblastoma (MDB), and ovarian cancer.

Structure: 88 kD armadillo repeat containing protein with an unstructured N and C terminal.
Distribution: β-catenin localizes to cell-cell contacts (adherens junctions) and the cell membrane as well as the cytoplasmic pool of protein. β-catenin can also translocate to the nucleus and is in interphase found in puncta at the proximal end of centrioles. In mitosis, it localizes to the centrosomes at the spindle.
Function: Wnt signaling pathway, regulation of cell-cell adhesion, neurogenesis, transcription, transcription regulation, early embryonic patterning, asymmetric cell division, stem cell renewal, and the epithelial to mesenchymal transition.
Interaction: Wnt signaling pathway, apoptotic cleavage of cellular proteins, and EphB-EphrinB signaling.
