Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within pronephric distal tubule development. Predicted to be active in nucleus. Is expressed in several structures, including forebrain; forebrain neural keel; neural plate; presumptive telencephalon; and pronephros. Orthologous to human EMX1 (empty spiracles homeobox 1).
