Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within skeletal muscle cell differentiation. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Orthologous to human HLF (HLF transcription factor, PAR bZIP family member).
