Transcriptional regulator. Involved in the initiation of neuronal differentiation. 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. Binds to IEB1 and IEB2, which are short DNA sequences in the insulin gene transcription control region.
Phosphorylated following NGF stimulation.
Forms a heterodimer with ASH1 and TWIST2. Isoform E12 interacts with RALGAPA1 and FIGLA. Efficient DNA binding requires dimerization with another bHLH protein. Component of a nuclear TAL-1 complex composed at least of CBFA2T3, LDB1, TAL1 and TCF3. Interacts with NEUROD2, PTF1A and TGFB1I1. Forms a heterodimer with MYOG; heterodimerization enhances MYOG DNA-binding and transcriptional activities (By similarity). Homodimer. Heterodimer. Forms a heterodimer with NEUROD1; the heterodimer is inhibited in presence of ID2, but not NR0B2, to E-box element. Interacts with EP300 and UBE2I. Interacts with BHLHA9. Forms a heterodimer with ATOH8; repress transcription of TCF3 and TCF3/NEUROG3 dimer-induced transactivation of E box-dependent promoters (By similarity).
the 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors.
