    Summary
    Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including nervous system development; positive regulation of transcription by RNA polymerase II; and regulation of neural precursor cell proliferation. Predicted to be active in nucleus. Is expressed in several structures, including central brain primordium; ganglia; larval optic anlage; neuroblasts; and unpaired neurons. Used to study central nervous system cancer. Human ortholog(s) of this gene implicated in piebaldism. Orthologous to human SNAI2 (snail family transcriptional repressor 2).
