Enables DNA-binding transcription activator activity, RNA polymerase II-specific and sequence-specific DNA binding activity. Acts upstream of or within several processes, including animal organ development; regulation of cell-matrix adhesion; and somitogenesis. Predicted to be located in nucleoplasm. Is expressed in several structures, including alimentary system; brain; embryo mesenchyme; genitourinary system; and skeletal musculature. Orthologous to human MYF5 (myogenic factor 5).
