Putative transcription factor. Probably involved in establishing polarity during leaf development through the gibberellic acid (GA) signaling pathway. Homo- and heterodimer with other ZFHD proteins. Interacts with MIF1, MIF2 and MIF3; these interactions prevent nuclear localization and DNA-binding to inhibit transcription regulation activity. Binds to ZHD1, ZHD2, ZHD4, ZHD5, ZHD6, ZHD7 and ZHD8. Interacts with KIN10 and KIN11 (Ref.11). Interactions with MIF proteins prevent nuclear subcellular location and leads to a scattered repartition throughout the cytoplasm. Mostly expressed in rosettes (e.g. young leaves), flowers (e.g. styles), siliques and inflorescence. In young leaves, accumulates in the adaxial domain of leaf primordia and the rib meristem. By gibberellic acid (GA). The homeodomain differs form the typical one by having namely 4 instead of 3 extra amino acids inserted in the loop between helix 1 and helix 2. Truncated N-terminus.
