title: Sequence Fourier analysis of a specific protein-DNA (RNA) interaction; an intermolecular frequency symmetry.
abstract: Here, we first report that a specific protein-DNA (RNA) interaction between p53 protein and divergent I kappa B kinase interacting protein (IKIP)-Apaf1 DNA promoter region, and between poliovirus 3CD protein and the 5' terminal region of the RNA sequence can be successfully elucidated with a sequence Fourier analysis, alike various specific protein-protein interactions described previously. Based on these, the intermolecular frequency symmetry would be evolutionarily conserved in a specific interaction of the bioactive structure of various long-chain sequences. In addition, the symmetry is fairly sensitive to a substitution (or a point mutation) on the sequence.
