Enables E-box binding activity. Involved in positive regulation of DNA-binding transcription factor activity. Acts upstream of or within several processes, including nervous system development; positive regulation of neuron differentiation; and positive regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including alimentary system; central nervous system; embryo ectoderm; eye; and integumental system.
