Functioni

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 (By similarity). Binds to the consensus sequence CAC/GCTGT/C present, in the chymotrypsin, insulin, AP-4, and several other gene enhancer motifs (PubMed:2200736).By similarity1 Publication

Interactioni

Subunit structurei

Homodimer. Heterodimer. Forms a heterodimer with MYOG; heterodimerization enhances MYOG DNA-binding and transcriptional activities. Forms a heterodimer with ASH1 and TWIST2. Forms a heterodimer with NEUROD1; the heterodimer is inhibited in presence of ID2, but not NR0B2, to E-box element. Isoform E12 interacts with RALGAPA1 and FIGLA. Interacts with EP300, NEUROD2, PTF1A and TGFB1I1. Component of a nuclear TAL-1 complex composed at least of CBFA2T3, LDB1, TAL1 and TCF3. Efficient DNA binding requires dimerization with another bHLH protein (By similarity). Interacts with 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).By similarity1 Publication
