      Background InformationTCF4, also known as TCF7L2, is expressed widely during development. Gene targeting study indicates that it is required to maintain the crypt stem cells of the small intestine. TCF4 has many different splicing isoforms and they are expressed differentially in tissues and in cancers of different stages. Studies also indicate that variant of the TCF4 gene confers an increased risk of type 2 diabetes.

      Entrez Gene Number
      Entrez Gene SummarySOX-TCF_HMG-box, class I member of the HMG-box superfamily of DNA-binding proteins. These proteins contain a single HMG box, and bind the minor groove of DNA in a highly sequence-specific manner. Members include SRY and its homologs in insects and vertebrates, and transcription factor-like proteins, TCF-1, -3, -4, and LEF-1. They appear to bind the minor groove of the A/T C A A A G/C-motif.

      UniProt Number
      UniProt SummaryFUNCTION: 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 CCTTTGATC 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 (By similarity). Necessary for the maintenance of the epithelial stem-cell compartment of the small intestine.
      SIZE: 619 amino acids; 67919 Da
      SUBUNIT: Interacts with TGFB1I1. Interacts with CTNNB1 (via the armadillo repeat); forms stable transcription complex. Interacts with EP300 (By similarity).
      SUBCELLULAR LOCATION: Nucleus. Note=Diffuse pattern. Colocalizes with SUMO1 and PIAS4 in a subset of PML (promyelocytic leukemia) nuclear bodies (By similarity).
      TISSUE SPECIFICITY: 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.
      DISEASE: 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).
      SIMILARITY: Contains 1 HMG box DNA-binding domain.
      Molecular WeightMr 66 kDa
