Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including positive regulation of myoblast fusion; response to activity; and skeletal muscle tissue regeneration. Predicted to be located in nucleus. Is expressed in several structures, including mesoderm; musculature system; myoblast; post-vent region; and trunk. Orthologous to human MYOG (myogenin).
