AS-C proteins are involved in the determination of the neuronal precursors in the peripheral nervous system and the central nervous system.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.
