Transcription factor E2-alpha (TCF3)

Transcriptional regulator. Involved from 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 premature B-cell differentiation. Dimers bind DNA on E- box motifs: 5'-CANNTG-3'.
