Protein function

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.

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. TCF3-PBX1 transforms cells by constitutively activating transcription of genes regulated by PBX1 or by other members of the PBX protein family (PubMed:1967983, PubMed:1671560). Translocation t(17;19)(q22;p13.3) with HLF (PubMed:1386162). Inversion inv(19)(p13;q13) with TFPT (PubMed:10086727). .

Protein sequence and domain

the 9aaTAD motif is a transactivation domain present in a large number of yeast and animal transcription factors. / Contains 1 bHLH (basic helix-loop-helix) domain.

Protein post-translational modifications

Phosphorylated following NGF stimulation.
