Figure 1.

Schematic representation of the DOF transcription factor structure. The DOF zinc finger domain, nuclear localization signal, and transcriptional activation domain are shown in blue, green, and yellow, respectively. The amino acid sequence in the zinc finger domain of DOF is represented by abbreviations, the zinc coordination is shown in bright green, the position of the four cysteines in the zinc finger structure is shown in red, the question mark represents any amino acid, and the tryptophan residue mentioned in the second part is shown in purple.
