CC -!- FUNCTION: Probable transcription activator that binds to the DNA
CC sequence 5'-CAAT[AT]ATTG-3'. May be involved in the regulation of
CC gibberellin signaling. {ECO:0000269|PubMed:10732669,
CC ECO:0000269|PubMed:18049796}.
CC -!- SUBUNIT: Homodimer (Probable). May form a heterodimer with HOX5.
CC {ECO:0000269|PubMed:10732669, ECO:0000305}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00108,
CC ECO:0000269|PubMed:18049796}.
CC -!- TISSUE SPECIFICITY: Expressed in leaf and floral organ primordia,
CC floral meristems, embryonic axis and cells surrounding the vascular
CC bundles. Expressed in the vasculature of roots, stem, leaves and
CC spikelets, and in the vascular bundle of the scutellum in embryos.
CC {ECO:0000269|PubMed:10732669, ECO:0000269|PubMed:17999151,
CC ECO:0000269|PubMed:18049796}.
CC -!- INDUCTION: By gibberellin. Down-regulated in leaves by drought stress.
CC {ECO:0000269|PubMed:17999151, ECO:0000269|PubMed:18049796}.
CC -!- SIMILARITY: Belongs to the HD-ZIP homeobox family. Class I subfamily.
CC {ECO:0000305}.
