TCF-3 (N601) polyclonal antibody

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.
