Rous sarcoma virus genome is terminally redundant: the 3' sequence.
A sequence of 20 nucleotide residues immediately adjacent to the 3'-terminal poly(A) in Rous sarcoma virus (Prague strain, subgroup C) 35S RNA has been determined by extension of a riboguanylic acid-terminated oligothymidylic acid primer hybridized at the 5' end of the 3'-terminal poly(A) with purified reverse transcriptase (RNA-directed DNA polymerase; deoxynucleosidetriphosphate:DNA deoxynucl...
متن کاملA possible mechanism of RNA replication in Rous sarcoma virus.
Partially separated double-stranded RNA from purified Rous sarcoma virus, Schmidt.Ruppin strain, was observed by electron microscopy utilizing 8.M urea and protein monolayer technique. Furthermore, viruses in pair were frequently and viruses with two nuc1eoids were occasionally observed in ultrathin. sectioned specimens of chick cells transformed by RSV. From these results taking other reports ...
متن کاملIdentification of the 5' end of Rous sarcoma virus RNA.
The 5'-terminal triphosphate of the 35S RNA isolated from Rous sarcoma virus is blocked by 7-methylguanosine in 5' linkage with the penultimate nucleoside which is methylated in the 2'-O-ribose position, a type of endgroup found in all animal mRNAs investigated during the past year. The specific nuclease-resistant terminal fragment of RSV RNA has the structure 7mG5'ppp5'GmpCp-. This finding sup...
متن کاملStructural characterization of the Rous sarcoma virus RNA stability element.
In eukaryotic cells, an mRNA bearing a premature termination codon (PTC) or an abnormally long 3' untranslated region (UTR) is often degraded by the nonsense-mediated mRNA decay (NMD) pathway. Despite the presence of a 5- to 7-kb 3' UTR, unspliced retroviral RNA escapes this degradation. We previously identified the Rous sarcoma virus (RSV) stability element (RSE), an RNA element downstream of ...
متن کاملRous Sarcoma Virus RNA Stability Element Inhibits Deadenylation of mRNAs with Long 3′UTRs
All retroviruses use their full-length primary transcript as the major mRNA for Group-specific antigen (Gag) capsid proteins. This results in a long 3' untranslated region (UTR) downstream of the termination codon. In the case of Rous sarcoma virus (RSV), there is a 7 kb 3'UTR downstream of the gag terminator, containing the pol, env, and src genes. mRNAs containing long 3'UTRs, like those with...
