CC   -!- FUNCTION: Binds to the G-box-like motif (5'-ACGTGGC-3') of the chalcone
CC       synthase (CHS) gene promoter. G-box and G-box-like motifs are defined
CC       in promoters of certain plant genes which are regulated by such diverse
CC       stimuli as light-induction or hormone control.
CC   -!- SUBUNIT: Binds DNA as a dimer.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- SIMILARITY: Belongs to the bZIP family. {ECO:0000305}.
