Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in anatomical structure morphogenesis; cell differentiation; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within negative regulation of DNA-templated transcription; neural crest cell fate commitment; and regulation of neurogenesis. Predicted to be located in nucleus. Is expressed in ectoderm. Human ortholog(s) of this gene implicated in vitiligo. Orthologous to human FOXD3 (forkhead box D3).
