    See all beta Catenin primary antibodies
  • Description
    Rabbit polyclonal to beta Catenin (phospho Y142)
  • Host species
  • Specificity
    The antibody detects beta Catenin on SDS PAGE immunoblots of Hct116 src transformed cells treated with pervanadate, but not in control cells. Similar results were observed in other pervanadate treated cell lines, such as A431 and human endothelial cells. Immunogen sequence has one amino acid difference from a sequence around tyrosine 133 of human gamma Catenin. These human sequences are highly conserved in rat and mouse beta Catenins. Batches could vary in the level phospho Y133 of gamma catenin recognition.

  • Immunogen

    Phospho beta Catenin (Tyr 142) synthetic peptide (coupled to KLH) corresponding to amino acid residues around tyrosine 142 of human beta Catenin.

  • General notes

    Tyrosine phosphorylation of beta Catenin can regulate its interaction with critical components of adherens junctions. Both Fer and Fyn kinases phosphorylate tyrosine 142 in vitro and overexpression of these kinases in epithelial cells disrupts interactions between alpha and beta Catenins. The phosphorylation of tyrosine 142 may act as a switch from the adhesive to the transcriptional role of beta Catenin. Thus, site specific tyrosine phosphorylation of beta Catenin may regulate specific protein protein interactions, leading to changes in cell adhesion.

  • Function
    Key dowstream component of the canonical Wnt signaling pathway. In the absence of Wnt, forms a complex with 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. In the presence of Wnt ligand, CTNNB1 is not ubiquitinated and accumulates in the nucleus, where it acts as a coactivator for transcription factors of the TCF/LEF family, leading to activate Wnt responsive genes.
    Involved in the regulation of cell adhesion. The majority of beta-catenin is localized to the cell membrane and is part of E-cadherin/catenin adhesion complexes which are proposed to couple cadherins to the actin cytoskeleton.
  • Tissue specificity
    Expressed in several hair follicle cell types: basal and peripheral matrix cells, and cells of the outer and inner root sheaths. Expressed in colon.
  • Involvement in disease
    Defects in CTNNB1 are associated with colorectal cancer (CRC) [MIM:114500].
    Note=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.
    Defects in CTNNB1 are a cause of susceptibility to ovarian cancer (OC) [MIM:167000]. Ovarian cancer common malignancy originating from ovarian tissue. Although many histologic types of ovarian neoplasms have been described, epithelial ovarian carcinoma is the most common form. Ovarian cancers are often asymptomatic and the recognized signs and symptoms, even of late-stage disease, are vague. Consequently, most patients are diagnosed with advanced disease.
    Note=A chromosomal aberration involving CTNNB1 is found in salivary gland pleiomorphic adenomas, the most common benign epithelial tumors of the salivary gland. Translocation t(3;8)(p21;q12) with PLAG1.
  • Sequence similarities
    Belongs to the beta-catenin family.
    Contains 12 ARM repeats.
  • Post-translational
    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 the SCF(BTRC) E3 ligase complex when phosphorylated by GSK3B, leading to its degradation. Ubiquitinated by a E3 ubiquitin ligase complex containing UBE2D1, SIAH1, CACYBP/SIP, SKP1, APC and TBL1X, leading to its subsequent proteasomal degradation.
  • Cellular localization
    Cytoplasm. Nucleus. Cytoplasm > cytoskeleton. Cell junction > adherens junction. Cell junction. Cell membrane. 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. Interaction with EMD inhibits nuclear localization.

Customer reviews and Q&As


Please see below for our protocol for the Pervanadate Treatment of Cells.

- Pervanadate (100mM stock)
- 100uL 30% Hydrogen Peroxide (H2O2)
- 200uL 500mM Sodium Vanadate
- 700uL dH2O

Serum Starvation and Cell Stimulations:
1. Grow cells of interest to 80-90% confluency (adherent cells: A431, J774A.1, HUVEC, SYF, RSF, COS7, differentiated PC12) or medium to high cell density (suspension cells: Jurkat, K562, Sp2O, undifferentiated PC12) in culture dishes.

2. Cell stimulations for studies of phosphorylation can examine serum starved cells to reduce basal phosphorylation levels prior to the addition of stimulants.

3. For adherent cells, remove cell culture growth media and rinse cells once in serum-free containing media (usually DMEM or F12K). Next, add serum-free media to each dish and place cells in incubator for 2 hrs (most cell lines) or overnight (A431 only). After serum starvation, add stimulant (treated) or vehicle (control) at the concentration and time required: 1 mM Pervanadate in dH2O for 30 min. (Some cell lines may come off dish with this concentration).
