The DOF (DNA binding with One Finger) transcription factor (TF) family is characterized by a binding domain of 52 amino acid residues that is structured as a Cys2/Cys2 Zn2+ finger that recognizes the common core 5?-T/AAAAG-3? in the promoter regions of their target genes. DOF TFs have been associated with biological processes exclusive to higher plants and their close ancestors (algae, mosses and ferns)
