Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in cell differentiation and negative regulation of transcription by RNA polymerase II. Predicted to be located in nucleoplasm. Is expressed in brain; branchial arch; jaw; limb ectoderm; and urinary system. Human ortholog(s) of this gene implicated in orofacial cleft 15. Orthologous to human DLX4 (distal-less homeobox 4).
