    basic FUNCTION
  • playing a role in the establishment of the mature T cell phenotype
  • can function with CTNNB to mediate canonical Wnt signalling; however, deletion of CTNNB does not affect T-cell development
  • initiates T(H)2 differentiation of activated CD4(+) T cells by promoting GATA-3 expression and suppressing IFN-gamma expression
  • its function to establish CD8 T cell memory is dependent on the catenin-binding domain in TCF7 and requires the TCF7 coactivators and Wnt signaling intermediates beta-catenin and gamma-catenin
  • critical player in a transcriptional program that regulates memory CD8 differentiation and longevity
  • critical regulator in T-cell specification
  • marked requirement at very early stages of T-cell development, which was clearly revealed when TCF7-deficient progenitors were placed in competition with TCF7-sufficient cells
  • critical regulator that is not only essential for normal T-cell development but is sufficient to establish many components of T-cell identity
  • TCF7-mediated repression of IL17 is critical for peripheral T cells to generate balanced immune responses
  • required at the earliest phase of T-cell determination for progression beyond the early thymic progenitor stage
  • important regulator of the switch of self-renewal and differentiation in a multipotential hematopoietic cell line
  • TCF7 and CTNNB1 regulate the generation of PLZF-expressing thymocytes and thereby facilitate the generation of memory-like CD8 T cells in the thymus
  • essential role for TCF7 and LEF1 in development of NKT cells
  • CELLULAR PROCESS nucleotide, transcription, regulation

    protein
  • critical factor to repress IL17 gene locus by chromatin modifications during T cell development
  • TCF7 and RUNX1 bind to each other promoter regions and that TCF7 is necessary for the production of the short isoforms, but not the long isoforms of RUNX1
  • UCHL5 interacts with TCF7 (formerly named Tcf1) to activate Wnt signalling
  • cell & other
