ターゲット情報

  • 機能Participates in the Wnt signaling pathway and modulates MYC expression by binding to its promoter in a sequence-specific manner. Acts as repressor in the absence of CTNNB1, and as activator in its presence. Activates transcription from promoters with several copies of the Tcf motif 5'-CCTTTGATC-3' in the presence of CTNNB1. TLE1, TLE2, TLE3 and TLE4 repress transactivation mediated by TCF7L2 and CTNNB1. Expression of dominant-negative mutants results in cell-cycle arrest in G1. Necessary for the maintenance of the epithelial stem-cell compartment of the small intestine.
  • 組織特異性Detected in epithelium from small intestine, with the highest expression at the top of the crypts and a gradient of expression from crypt to villus. Detected in colon epithelium and colon cancer, and in epithelium from mammary gland and carcinomas derived therefrom.
  • 関連疾患Note=Constitutive activation and subsequent transactivation of target genes may lead to the maintenance of stem-cell characteristics (cycling and longevity) in cells that should normally undergo terminal differentiation and constitute the primary transforming event in colorectal cancer (CRC).
    Genetic variations in TCF7L2 are associated with susceptibility to non-insulin-dependent diabetes mellitus (NIDDM) [MIM:125853]. NIDDM is characterized by an autosomal dominant mode of inheritance, onset during adulthood and insulin resistance.
  • 配列類似性Belongs to the TCF/LEF family.
    Contains 1 HMG box DNA-binding domain.
  • 発生段階Highly expressed in crypt regions and barely detectable in villi in epithelium from fetal small intestine at week 16. At week 22 expression in villi had increased strongly.
  • ドメインThe promoter-specific activation domain interacts with the transcriptional coactivator EP300.
  • 翻訳後修飾In vitro, phosphorylated by TNIK.
    Polysumoylated. Sumoylation is enhanced by PIAS family members and desumoylated by AXAM/SENP2. Sumoylation/desumoylation regulates TCF4 transcription activity in the Wnt signaling pathway without altering interaction with CTNNB1 nor binding DNA.
  • 細胞内局在Nucleus > PML body. Diffuse pattern. Colocalizes with SUMO1 and PIAS4 in a subset of PML (promyelocytic leukemia) nuclear bodies.

Thank you for your enquiry. Thank you for highlighting these key differences and confusion in the TCF4 nomenclature to me. I have looked into the details of these antibodies and as you highlight ab2233 was raised against TCF4: a bHLH transcription ...
