The autoinhibition of Ets1 is mediated by structural coupling of the regions flanking the Ets domain. The inhibitory regions are folded as helices HI1 and HI2 N-terminal to the ETS domain and as H4 C-terminal to the ETS domain, which are packed together to form an inhibitory module. This domain represents the N-terminal flanking region of Ets domain which contains the residues forming HI1 and HI2 helices and additional residues(244-301) N-terminal to HI1. HI1 and HI2 exert the autoinhibitory function by directing the inhibitory residues N-terminal to HI1 to mask the Ets domain DNA-binding surface. These residues are flexible and function by masking the DNA-binding surface of the Ets domain. Phosphorylation of serine residues present in this region enhances autoinhibition dramatically. These inhibitory sequences are required for cooperative DNA binding [5].
