Functional interaction between p53, the TATA-binding protein (TBP), andTBP-associated factors in vivo.

abstract：:Cytosine methylation at CpG dinucleotides is thought to cause more than one-third of all transition mutations responsible for human genetic diseases and cancer. We investigated the methylation status of the CpG dinucleotide at codon 248 in exon 7 of the p53 gene because this codon is a hot spot for inactivating mutati...
