function:Inhibits DNA binding of TCF3/E47 homodimers and TCF3 (E47)/NEUROD1 heterodimers and acts as a strong repressor of Neurod1 and Myod-responsive genes, probably by heterodimerization with class a basic helix-loop-helix factors. Despite the presence of an intact basic domain, does not bind to DNA.,similarity:Contains 1 basic helix-loop-helix (bHLH) domain.,tissue specificity:Brain-specific, with the highest expression in the cerebellum.,
