      DescriptionAnti-β-Catenin (NT) Antibody, clone E247, rabbit monoclonal
      Alternate Names

      • catenin (cadherin-associated protein), beta 1, 88kDa
      • catenin beta-1
      Background InformationΒ-Catenin links Cadherin cell adhesion proteins to the cytoskeleton and has recently been implicated in the Wnt/Wingless signaling pathway and in the progression of neoplasia. β-Catenin associates with the tumor suppressor Adenomatous Polypopsis Coli (APC) and functions as a co-activator of the TCF transcription factor family. It is regulated by Glycogen Synthase Kinase (GSK) 3b, which phosphorylates and targets β-Catenin for ubiquitin-mediated proteolysis. Stabilization of β-Catenin, either by Wnt-mediated inhibition of GSK3b or by mutation (as found in numerous colorectal tumors and melanoma cell lines), results in activation of TCF responsive genes which are thought to play key roles in development and cancer progression. δ-Catenin (NPRAP/Neurojungin), a member of the p120 Catenin subfamily, is a structural protein involved in neuronal development. It interacts with Actin, Cortactin and Src Kinases to promote neurite elongation or branching, depending upon its phosphorylation state.

      Entrez Gene Number
      Entrez Gene SummaryBeta-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 Number
      UniProt SummaryFUNCTION: Involved in the regulation of cell adhesion and in signal transduction through the Wnt pathway.
      SUBUNIT STRUCTURE: 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 CHD8. Binds CTNNBIP and EP300. CTNNB1 forms a ternary complex with LEF1 and EP300 that is disrupted by CTNNBIP1 binding By similarity. Interacts with TAX1BP3 (via the PDZ domain); this interaction inhibits the transcriptional activity of CTNNB1 By similarity. Interacts with AJAP1, BAIAP1, CARM1, CTNNA3, CXADR and PCDH11Y. Binds SLC9A3R1. Interacts with GLIS2 and MUC1. Interacts with SLC30A9. Interacts with XIRP1 By similarity. Interacts with PTPRU (via the cytoplasmic juxtamembrane domain).
      SUBCELLULAR LOCATION:Cytoplasm. Nucleus. Cytoplasm › cytoskeleton. 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 and MUC1 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: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.
