Predicted to enable DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within skeletal muscle cell differentiation. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including alimentary system; genitourinary system; heart; nervous system; and sensory organ. Orthologous to human HLF (HLF transcription factor, PAR bZIP family member). [provided by Alliance of Genome Resources, Apr 2022]
