Homology modeling using the p63 and p73 DNA-binding domains. From top: the p53, p63, and p73 dimer PWMs from this study and the corresponding p53 TRANSFAC logo from entry V$P53_02. The p63 and p73 PWMs were obtained by homology modeling using the p53 binding domain. For detailed presentations, the logos were computed by plotting the frequencies and not by calculating relative entropy as in Fig. 2.
