Description: Rabbit IgG polyclonal antibody for Catenin beta-1(CTNNB1) detection. Tested with WB, IHC-P, IHC-F, ICC in Human, Mouse, Rat.

Background: Catenins are proteins found in complexes with cadherin cell adhesion molecules of animal cells. The first two catenins that were identified became known as alpha-catenin and beta-catenin. Alpha-catenin can bind to beta-catenin and can also bind actin. Beta-catenin binds the cytoplasmic domain of some cadherins. Beta-catenin is an adherens junction protein. It plays an important role in various aspects of liver biology including liver development(both embryonic and postnatal), liver regeneration following partial hepatectomy. HGF-induced hepatpomegaly, liver zonation, and pathogenesis of liver cancer.

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.
