Binds specifically to oligomers of E-box motifs. May play important roles during development of the nervous system as well as in other organ systems. Efficient DNA binding requires dimerization with another bHLH protein. Forms homo- or hetero-oligomers with myogenin, E12 and ITF2 proteins. Interacts with PTF1A. Note: This description may include information from UniProtKB.
Molecular Function: bHLH transcription factor binding; protein binding; protein heterodimerization activity; protein homodimerization activity; SMAD binding; transcription factor activity; transcription factor binding
Biological Process: immune response; muscle development; positive regulation of neuron differentiation; positive regulation of transcription from RNA polymerase II promoter; regulation of transcription from RNA polymerase II promoter
