Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within intra-Golgi vesicle-mediated transport. Predicted to be located in Golgi membrane. Predicted to be active in nucleus. Is expressed in several structures, including adaxial cell; cardiovascular system; immature eye; musculature system; and notochord. Orthologous to human CUX1 (cut like homeobox 1).
