RT   transcriptional regulation of the homeobox gene Bkn3.";
RL   Plant J. 34:813-826(2003).
CC   -!- FUNCTION: Transcriptional regulator that specifically binds to GA-rich
CC       elements (GAGA-repeats) present in regulatory sequences of genes
CC       involved in developmental processes. Positively regulates the homeotic
CC       gene BKN3. {ECO:0000269|PubMed:12795701}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000269|PubMed:12795701}.
CC   -!- TISSUE SPECIFICITY: Ubiquitously expressed.
CC       {ECO:0000269|PubMed:12795701}.
CC   -!- SIMILARITY: Belongs to the BBR/BPC family. {ECO:0000305}.
