Fig. 4: FOXO4-DRI directly binds to p53TAD.

a Sequence of FOXO4-DRI. b 1H,15N HSQC spectra of 15N-labeled p531–94 in the absence (black) or presence of one stoichiometric equivalent of FOXO4-DRI (orange) and corresponding CSPs. c 1H,15N HSQC spectra of 15N-labeled p53TAD2 in the absence (black) or presence of one stoichiometric equivalent of FOXO4-DRI (orange). d 1H,15N HSQC spectra of 15N-labeled FOXO4-LRI in the absence (black) or presence of one stoichiometric equivalent of D-p53TAD2 (blue) and corresponding CSPs.
