CC   -!- FUNCTION: Transcriptional regulator that interacts with specific sites
CC       in the control region of the cyIIIa actin gene. Also binds specifically
CC       to similar target sites located in the regulatory region of the SM50
CC       gene.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- SIMILARITY: Belongs to the NRF1/Ewg family. {ECO:0000305}.
