The human lung carcinomas PR310 and PR371 contain activated c-K-rasoncogenes. The oncogene of PR371 was found to present a mutation at codon 12 of the first coding exon which substitutes cysteine for glycine in the encoded p21 protein. We report here that the transforming gene of PR310 tumor contains a mutation in the second coding exon. An A→T transverslon at codon 61 results in the incorporation of histidine instead of glutamine in the c-K-rasgene product. By constructing c-K-ras/c-H-raschimeric genes we show that this point mutation is sufficient to confer transforming potential torasgenes, and that a hybridrasgene coding for a protein mutant at both codons 12 and 61 is also capable of transforming NIH3T3 cells. The relative transforming potency of p21 proteins encoded byrasgenes mutant at codons 12, 61 or both has been analyzed. Our studies also show that the coding exons ofrasgenes, including the fourth, can be interchanged and the chimeric p21rasproteins retain their oncogenic ability in normal rodent established cell lines.
