== Publication Abstract from PubMed ==
The Nrf2 transcription factor, which plays important roles in oxidative and xenobiotic stress, is negatively regulated by the cytoplasmic repressor Keap1. The beta-propeller/Kelch domain of Keap1, which is formed by the double-glycine repeat and C-terminal region domains (Keap1-DC), interacts directly with the Neh2 domain of Nrf2. The nuclear oncoprotein prothymosin alpha (ProTalpha) also interacts directly with Keap1 and may play a role in the dissociation of the Keap1-Nrf2 complex. The structure of Keap1-DC complexed with a ProTalpha peptide (amino acids 39-54) has been determined at 1.9 A resolution. The Keap1-bound ProTalpha peptide possesses a hairpin conformation and binds to the Keap1 protein at the bottom region of the beta-propeller domain. Complex formation occurs as a consequence of their complementary electrostatic interactions. A comparison of the present structure with recently reported Keap1-DC complex structures revealed that the DLG and ETGE motifs of the Neh2 domain of Nrf2 and the ProTalpha peptide bind to Keap1 in a similar manner but with different binding potencies.
