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 negative regulation of transcription by RNA polymerase II and regulation of neuron migration. Located in nucleus. Is expressed in future hindbrain; nervous system; and retina. Orthologous to human SCRT2 (scratch family transcriptional repressor 2). [provided by Alliance of Genome Resources, Apr 2022]
