RT   "The HBP-1 family of wheat basic/leucine zipper proteins interacts with
RT   overlapping cis-acting hexamer motifs of plant histone genes.";
RL   J. Biol. Chem. 269:9974-9985(1994).
CC   -!- FUNCTION: Transcriptional activator that binds specifically to the DNA
CC       sequence 5'-TGACG-3'. Recognizes ocs elements like the as-1 motif of
CC       the cauliflower mosaic virus 35S promoter. Binding to the as-1-like cis
CC       elements mediate auxin- and salicylic acid-inducible transcription.
CC       Binds to the hexamer motif 5'-ACGTCA-3' of histone gene promoters.
CC   -!- SUBUNIT: Binds DNA as a dimer.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- SIMILARITY: Belongs to the bZIP family. {ECO:0000305}.
