Putative transcription factor. Homo- and heterodimer with other ZFHD proteins (By similarity). Interacts with MIF1 and MIF2; these interactions prevent nuclear localization and DNA-binding to inhibit transcription regulation activity. Binds to ZHD2, ZHD3, ZHD4, ZHD5, ZHD6, ZHD7, ZHD8, ZHD9, 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. 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.
