  • Function

    Heterodimers between TCF3 and tissue-specific basic helix-loop-helix (bHLH) proteins play major roles in determining tissue-specific cell fate during embryogenesis, like muscle or early B-cell differentiation. Dimers bind DNA on E-box motifs: 5'-CANNTG-3'. Binds to the kappa-E2 site in the kappa immunoglobulin gene enhancer.
  • Involvement in disease

    Note=Chromosomal aberrations involving TCF3 are cause of forms of pre-B-cell acute lymphoblastic leukemia (B-ALL). Translocation t(1;19)(q23;p13.3) with PBX1; Translocation t(17;19)(q22;p13.3) with HLF. Inversion inv(19)(p13;q13) with TFPT.
  • Sequence similarities

    Contains 1 basic helix-loop-helix (bHLH) domain.
  • Domain

    the 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors.
  • Post-translational

    Phosphorylated following NGF stimulation.
  • Cellular localization
