Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and identical protein binding activity. Acts upstream of or within positive regulation of transcription by RNA polymerase II. Predicted to be active in nucleus. Is expressed in several structures, including central nervous system; early conceptus; future brain; ovary; and vomeronasal organ. Orthologous to human TFAP2E (transcription factor AP-2 epsilon).
