Transcriptional regulator that specifically binds to GA-rich elements (GAGA-repeats) present in regulatory sequences of genes involved in developmental processes. Expressed in seedlings, leaves and pistils. Detected in the base of flowers and tips of carpels, in sepal and petal vasculature, in pollen grains, in young rosette, in the lateral and tip of primary roots, and in ovule at the exception of the outer integument. Belongs to the BBR/BPC family.
