Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within negative regulation of transcription by RNA polymerase II and regulation of neuron migration. Located in nucleus. Is expressed in future hindbrain; genitourinary system; lung epithelium; nervous system; and retina. Orthologous to human SCRT1 (scratch family transcriptional repressor 1).
