Abstract

In the original language

Recently we have shown that wild-type human p53 protein binds preferentially to supercoiled (sc) DNA in vitro in both the presence and absence of the p53 consensus sequence (p53CON). This binding produces a ladder of retarded bands on an agarose gel. The intensity and the number of these hands are decreased by physiological concentrations of zinc ions. At higher zinc concentrations, binding of p53 to scDNA is completely inhibited.
