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 anthers, in pollen grains, in young rosette, in leaf vasculature, in the lateral and primary roots, in embryo sac, and in the whole ovule. Belongs to the BBR/BPC family.
