anti-CTNNB1 antibody
Beta-catenin is an adherens junction protein. Adherens junctions (AJs; also called the zonula adherens) are critical for the establishment and maintenance of epithelial layers, such as those lining organ surfaces. AJs mediate adhesion between cells, communicate a signal that neighboring cells are present, and anchor the actin cytoskeleton. In serving these roles, AJs regulate normal cell growth and behavior.

NCBI Summary for CTNNB1
The protein encoded by this gene 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. Finally, this protein binds to the product of the APC gene, which is mutated in adenomatous polyposis of the colon. Mutations in this gene are a cause of colorectal cancer (CRC), pilomatrixoma (PTR), medulloblastoma (MDB), and ovarian cancer. Three transcript variants encoding the same protein have been found for this gene.[provided by RefSeq, Oct 2009]
UniProt Comments for CTNNB1
CTNNB1: a regulator of cell adhesion and a key downstream effector in the Wnt signaling pathway. Implicated early embryonic development and tumorigenesis. Phosphorylated and destabilized by CK1 and GSK-3beta. Stabilized cytoplasmic beta-catenin is a hallmark of a variety of cancers. Stabilized beta-catenin translocates to the nucleus, where it acts as a transcriptional activator of T-cell factor (TCF)-regulated genes. Interacts with the PDZ domain of TAX1BP3, inhibiting its transcriptional activity. Two alternatively spliced human isoforms have been described.
