Putative transcription factor. Binds DNA at 5'-ATTA-3' consensus promoter regions. Regulates floral architecture and leaf development. Regulators in the abscisic acid (ABA) signal pathway that confers sensitivity to ABA in an ARF2-dependent manner. 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, ZHD10 and ZHD11. Interactions with MIF proteins prevent nuclear subcellular location and leads to a scattered repartition throughout the cytoplasm. Mostly expressed in flowers and inflorescence. Repressed by abscisic acid (ABA) and ARF2. 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. Increased resistance to abscisic acid (ABA) in the seed germination and primary root growth.
