    Role of tumor suppressor p53 domains in selective binding to supercoiled DNA.

  • Original language description

    We showed 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 here that the p53 C- terminal domain (amino acids 347-382) and a p53 oligomeric state are important for SCS binding.Using electron microscopy we observed p53-scDNA nucleoprotein filaments produced by all the C-terminal proteins that displayed SCS binding in the gel electrophoresis experiments.
