Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II; positive regulation of transcription by RNA polymerase II; and skeletal muscle tissue development. Predicted to act upstream of or within several processes, including in utero embryonic development; nervous system development; and regulation of cell division. Predicted to be located in heterochromatin and nuclear speck. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in autosomal dominant non-syndromic intellectual disability 22. Orthologous to human ZBTB18 (zinc finger and BTB domain containing 18).
