Abstract

The nucleotide sequence of the src gene and flanking regions of the Schmidt-Ruppin strain of Rous sarcoma virus (SR-A) was determined. The src region of SR-A was very homologous to that of recovered avian sarcoma virus (rASV1441), with only 17 differences among 1,578 nucleotides. The size of the predicted protein was 526 amino acids in both viruses, of which 6 amino acids were different. The differences in nucleotides and amino acids between the two viruses localized within the 5' two-thirds of the src coding region. There were also viruses localized within the 5' two-thirds of the src coding region. There were also some differences in the region flanking the 5' end of src. Since rASVs are considered to be recombinatns between deletion mutants of SR-A and cellular-src (c-src) sequences, several segments of c-src DNA were also sequenced to understand the molecular basis for the recombination. At 14 of 17 bases where SR-A and rASV1441 differed, rASV1441 had the same sequence as c-src. Three of these sequences corresponded to sequences of oligonucleotides which were previously identified in RNAs of nearly all isolates of rASV but which were absent in SR-A RNA. In the 5'-flanking sequences of the src gene, c-src was more similar to rASV1441 than to SR-A. These results confirm the cellular origin of the src sequences of rASVs and provide information about the possible sites of the recombination.
