This work reports the identification of a T cell‐specific transcription factor, TCF‐1, binding to a downstream T lymphocyte‐specific enhancer element inCD3‐epsilon expression and identifies it as a Tcell‐ specific transcription factor which might play a role in the establishment of the mature T cell phenotype.Abstract:
CD3-epsilon expression is controlled by a downstream T lymphocyte-specific enhancer element. We report the identification of a T cell-specific transcription factor, TCF-1, binding to this element. The multimerized recognition motif of TCF-1 constituted a T cell-specific enhancer. Subsequent cloning of TCF-1 identified three splice alternatives. TCF-1 contained a single DNA-binding HMG box most closely related to similar boxes in the putative mammalian sex-determining gene SRY and in the Schizosaccharomyces pombe Mc mating type gene. TCF-1 mRNA was expressed uniquely in T lymphocytes. Upon cotransfection into non-T cells, TCF-1 could transactivate through its cognate motif. These results identify TCF-1 as a T cell-specific transcription factor, which might play a role in the establishment of the mature T cell phenotype.read more

Identification of c-MYC as a Target of the APC Pathway
Tong-Chuan He,Andrew B. Sparks,Carlo Rago,Heiko Hermeking,Leigh Zawel,Luis T. da Costa,Patrice J. Morin,Bert Vogelstein,Kenneth W. Kinzler +8 more
TL;DR: The c-MYC oncogene is identified as a target gene in this signaling pathway and shown to be repressed by wild-type APC and activated by beta-catenin, and these effects were mediated through Tcf-4 binding sites in the c- MYC promoter.

XTcf-3 Transcription Factor Mediates β-Catenin-Induced Axis Formation in Xenopus Embryos

TL;DR: It is proposed that signaling by beta-catenin involves complex formation with XT cf-3, followed by nuclear translocation and activation of specific XTcf-3 target genes, which suppresses endogenous axis specification upon injection into the dorsal blastomeres of a 4-cell-stage embryo.
