| Background Information | β-catenin plays a central role in cell adhesion, bridging between cadherins and actin cytoskeleton. These activities are regulated through its differential interaction with several molecular partners, including cell-cell adherens junction (AJ) molecules, components of its degradation complex, and transcription factors. β-Catenin is composed of three domains: a central armadillo repeat domain and two N- and C-terminal tails. β-catenin can be phosphorylated by serine-threonine kinase, such as GSK-3. The phosphorylated β-catenin affects the protein association of β-catenin to E-cadherin and α-cateinin that occurs in the cell. This process can be reversed by de-phosphorylation of β-catenin. |

| Entrez Gene Summary | 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. At several stages of embryogenesis, wound healing, and tumor cell metastasis, cells form and leave epithelia. This process, which involves the disruption and reestablishment of epithelial cell-cell contacts, may be regulated by the disassembly and assembly of AJs. AJs may also function in the transmission of the contact inhibition signal, which instructs cells to stop dividing once an epithelial sheet is complete.[supplied by OMIM] |

| UniProt Summary | FUNCTION: SwissProt: P35222 # Involved in the regulation of cell adhesion and in signal transduction through the Wnt pathway. SIZE: 781 amino acids; 85497 Da SUBUNIT: Two separate pools are found in the cytoplasm: one is PSEN1/cadherin/catenin complex which anchors to the actin cytoskeleton. The other pool is part of a large complex containing 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. Wnt- dependent activation of DVL antagonizes the action of GSK3B. When GSK3B activity is inhibited the complex dissociates, CTNNB1 is dephosphorylated and is no longer targeted for destruction. The stabilized protein translocates to the nucleus, where it binds TCF/LEF-1 family members, TBP, BCL9 and possibly also RUVBL1 and DUPLIN. Binds CTNNBIP and EP300. CTNNB1 forms a ternary complex with LEF1 and EP300 that is disrupted by CTNNBIP1 binding (By similarity). Interacts with the PDZ domain of TAX1BP3; this interaction inhibits the transcriptional activity of CTNNB1 (By similarity). Interacts with AJAP1, BAIAP1, CARM1, CTNNA3, CXADR and PCDH11Y. Binds SLC9A3R1. Interacts with GLIS2. Interacts with SLC30A9 (By similarity). SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Cytoplasmic when it is unstabilized (high level of phosphorylation) or bound to CDH1. Translocates to the nucleus when it is stabilized (low level of phosphorylation). Interaction with GLIS2 promotes nuclear translocation. TISSUE SPECIFICITY: Expressed in several hair follicle cell types: basal and peripheral matrix cells, and cells of the outer and inner root sheats. Expressed in colon. PTM: Phosphorylation by GSK3B requires prior phosphorylation of Ser-45 by another kinase. Phosphorylation proceeds then from Thr- 41 to Ser-37 and Ser-33. & EGF stimulates tyrosine phosphorylation. Phosphorylation on Tyr-654 decreases CDH1 binding and enhances TBP binding. & Ubiquitinated by a E3 ubiquitin ligase complex containing UBE2D1, SIAH1, CACYBP/SIP, SKP1A, APC and TBL1X (Probable). Its ubiquitination leads to its subsequent proteasomal degradation. DISEASE: "SwissProt: P35222 # Activating mutations in CTNNB1 have oncogenic activity resulting in tumor development. Somatic mutations are found in various tumor types, including colon cancers, ovarian and prostate carcinomas, hepatoblastoma (HB), hepatocellular carcinoma (HCC). HBs are malignant embryonal tumors mainly affecting young children in the first three years of life. & Defects in CTNNB1 are a cause of pilomatrixoma (PTR) [MIM:132600]; a common benign skin tumor. & Defects in CTNNB1 are a cause of medulloblastoma (MDB) [MIM:155255]. MDB is a malignant, invasive embryonal tumor of the cerebellum with a preferential manifestation in children. & A chromosomal rearrangement involving CTNNB1 may be a cause of salivary gland pleiomorphic adenomas (PA) [181030]. Pleiomorphic adenomas are the most common benign epithelial tumors of the salivary gland. Translocation t(3;8)(p21;q12) with PLAG1." SIMILARITY: SwissProt: P35222 ## Belongs to the beta-catenin family. & Contains 12 ARM repeats. |
