Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in muscle organ development and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within negative regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm; nucleoplasm; and plasma membrane. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in lethal congenital contracture syndrome. Orthologous to human ZBTB42 (zinc finger and BTB domain containing 42).
