Transformation associated p53 protein is encoded by a gene on human chromosome 17

The human gene for the transformation-associated p53 phosphoprotein (P53) was assigned to the short arm of chromosome 17 using human-rodent somatic cell hybrids and Southern filter hybridization of cell hybrid DNA. The filters were hybridized to radiolabeled DNA from a genomic clone which contained P53 nucleotide sequences. Hybridization of the probe to a 2.5-kb human DNA fragment in HindIII-digested DNA was used to identify the human P53 gene.
