Protein: Transcription factor E2-alpha (Immunoglobulin-enhancer-binding factor E12/E47) (Transcription factor 3) (TCF-3) (Transcription regulator Pan) (P98180)
Organism: Mesocricetus auratus (Golden hamster)
Function: Transcriptional regulator. Involved in the initiation of neuronal differentiation and mesenchymal to epithelial transition (By similarity). 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 (By similarity). Together with TCF15, required for the mesenchymal to epithelial transition (By similarity). Dimers bind DNA on E-box motifs: 5'-CANNTG-3' (By similarity). Binds to the kappa-E2 site in the kappa immunoglobulin gene enhancer (By similarity). Binds to IEB1 and IEB2, which are short DNA sequences in the insulin gene transcription control region (By similarity).
Subcellular location: Nucleus {ECO:0000250|UniProtKB:P15806}.
