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. |
Post Translational Modifications | In vitro, phosphorylated by TNIK. Phosphorylated at Thr-201 and/or Thr-212 by NLK. Phosphorylation by NLK at these sites inhibits DNA-binding by TCF7L2/TCF4, thereby preventing transcriptional activation of target genes of the canonical Wnt/beta-catenin signaling pathway. Polysumoylated. Sumoylation is enhanced by PIAS family members and desumoylation is enhanced by SENP2. Sumoylation/desumoylation regulates TCF7L2/TCF4 transcription activity in the Wnt/beta-catenin signaling pathway without altering interaction with CTNNB1 nor binding to DNA. |
Function | Participates in the Wnt signaling pathway and modulates MYC expression by binding to its promoter in a sequence-specific manner. Acts as a 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/TCF4 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. |
