The present work relates to the solution structure of the DNA binding domain (DBD) of the p63 protein, which has been determined by NMR spectroscopy. Having achieved an almost complete assignment of all resonances (cf. BMRB-ID 11012) of the 27 kDa protein, the structure of the p63 DBD (cf. PDB-ID 2RMN) could be obtained with outstanding precision. Moreover, the binding of the p63 DBD to the p53 DBD and double-stranded DNA was examined using chemical shift analysis. While binding to the p53 DBD could not be detected, the binding to ds-DNA was expectedly strong. Using paramagnetic spin labeling it could be shown that the p63 DBD has the same binding site to Bcl-xL as the p53 DBD.
