Enables E-box binding activity and chromatin binding activity. Involved in positive regulation of DNA-binding transcription factor activity; positive regulation of neuron differentiation; and positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including inner ear morphogenesis; positive regulation of exit from mitosis; and regulation of neuron differentiation. Located in perikaryon. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Orthologous to human NEUROG1 (neurogenin 1).
