Enables DNA-binding transcription factor activity, RNA polymerase II-specific; chromatin binding activity; and cis-regulatory region sequence-specific DNA binding activity. Involved in neural retina development; positive regulation of transcription by RNA polymerase II; and ventral spinal cord interneuron fate commitment. Acts upstream of or within neuron fate commitment. Located in nucleus. Is expressed in several structures, including alimentary system; central nervous system; eye; metanephros; and respiratory system. Orthologous to human FOXN4 (forkhead box N4).
