1-260aa, Full length protein. MW: 27,695 Da. Purity >85% (SDS-PAGE). This gene is a member of the basic helix-loop-helix (BHLH) family of transcription factors. It activates transcription by binding to the E box (5 -CANNTG-3 ). Dimerization with other BHLH proteins is required for efficient DNA binding. Involved in the determination of the neuronal precursors in the peripheral nervous system and the central nervous system.
