    Summary
    Enables POZ domain binding activity; protein homodimerization activity; and sequence-specific DNA binding activity. Involved in embryonic pattern specification; heterochromatin formation; and imaginal disc-derived wing morphogenesis. Located in nucleus. Part of PcG protein complex. Is expressed in several structures, including amnioserosa; gnathal segment; imaginal disc; outer photoreceptor cell; and photoreceptor precursor cell.
