Cloning and nucleotide sequences of cDNAs spanning the splice junctions of Rous sarcoma virus mRNAs.

Abstract

The cDNAs corresponding to the 5' ends of the mRNAs coding for the envelope protein precursor (gPr92env) of the B77 strain and the transforming protein (pp60src) of the Prague B strain of Rous sarcoma virus were cloned into pBR322, and the nucleotide sequences surrounding the splice junctions were determined. Both mRNAs are products of single splicing events from a common donor splice site at nucleotide 398 from the 5' end of the RNA to acceptor splice sites at nucleotides 5078 and 7054 for the env and src mRNAs, respectively. These results confirm and extend previous conclusions based on peptide mapping and single-strand nuclease mapping. Compared with the sequence of the Prague C genome RNA, the B77 strain contains a 6-nucleotide deletion in the sequence corresponding to the hydrophobic portion of the signal peptide of the envelope protein precursor.
