Proposed model of functional domains in HD-Zip I transcription factors. The in silico analysis conducted on a considerably large dataset of HD-Zip I transcription factors allowed us to postulate a generalized functional model of this family of proteins. This is supported to some extent by previous studies and the experimental results presented in this work. The well characterized HD-Zip domains are in charge of DNA binding and dimerization, an AHA motif in the CTR is responsible for activation, and the NTR and CTR are regions potentially phosphorylated and sumoylated, depending on the group, thus playing a regulatory role.
