We showed previously that bacterially expressed full-length human wild-type p53b(1-393) binds selectively to supercoiled (sc)DNA in sc/linear DNA competition experiments, a process we termed supercoil-selective (SCS) binding. Using p53 deletion mutants and pBluescript scDNA (lacking the p53 recognition sequence) at native superhelix density we demonstrate(More)
Hot spot mutant p53 (mutp53) proteins exert oncogenic gain-of-function activities. Binding of mutp53 to DNA is assumed to be involved in mutp53-mediated repression or activation of several mutp53 target genes. To investigate the importance of DNA topology on mutp53-DNA recognition in vitro and in cells, we analyzed the interaction of seven hot spot mutp53(More)
Electrochemical analysis of nucleic acids, proteins and polysaccharides represents an interesting, although not widely spread alternative to current methods based predominantly on optical detection because it offers a relatively inexpensive, fast and instrumentally simple detection of parallel samples on miniaturized chips, ideal for personalized medicine(More)
