Enables DNA-binding transcription activator activity, RNA polymerase II-specific and chromatin binding activity. Acts upstream of or within several processes, including odontoblast differentiation; odontogenesis of dentin-containing tooth; and placenta development. Located in nucleus. Is expressed in several structures, including brain; branchial arch; genitourinary system; jaw; and sensory organ. Human ortholog(s) of this gene implicated in amelogenesis imperfecta type 4 and trichodontoosseous syndrome. Orthologous to human DLX3 (distal-less homeobox 3).
