Target Background

Participates in the Wnt signaling pathway. Binds to DNA and acts as a repressor in the absence of CTNNB1, and as an activator in its presence. Necessary for the terminal differentiation of epidermal cells, the formation of keratohyalin granules and the development of the barrier function of the epidermis. Down-regulates NQO1, leading to increased mitomycin c resistance.
Gene References into Functions
  1. HIPK2 up-regulates transcription by phosphorylating TCF3, a transcriptional repressor, but inhibits transcription by phosphorylating LEF1, a transcriptional activator. PMID: 21285352
  2. Tcf3is partially responsible for the butyrate-resistant phenotype of colorectal cancer cells, as this DNA-binding protein suppresses the hyperinduction of Wnt activity by butyrate. PMID: 23063976
  3. Our results identify TCF3 as a central regulator of tumor growth and initiation. PMID: 23090119
  4. TCF3, a novel positive regulator of osteogenesis, plays a crucial role in miR-17 modulating the diverse effect of canonical Wnt signaling in different microenvironments. PMID: 23492770
  5. TCF/TLE tetramer complex promotes structural transitions of chromatin to mediate repression. PMID: 24596249
  6. These results indicate that a dynamic interplay of TCF transcription factors governs MYC gene expression in colorectal cancers. PMID: 25659031
  7. TCF7L1, a Wnt pathway repressor, buffers CTNNB1/TCF target gene expression to promote CRC growth PMID: 27333864
  8. TCF7L1 plays a major role in maintaining hESC pluripotency, which has implications for human development during gastrulation PMID: 29361574
  9. Through transcriptome profiling and combined gain- and loss-of-function studies, the authors identified LCN2 as a major downstream effector of TCF7L1 that drives tumor growth. PMID: 28467300
  10. report the identification of two independent missense variants in human TCF7L1, p.R92P and p.R400Q, in a cohort of patients with forebrain and/or pituitary defects PMID: 26764381
  11. No difference in nuclear beta-catenin signal intensity was found, which may be caused by an alteration in Wnt pathway in microsatellite stable sporadic tumors by unknown mechanisms leading to lower TCF-3, 4 protein expression. PMID: 20532534
