Rous Sarcoma Virus DR Posttranscriptional Elements Use a Novel RNA Export Pathway
15 Oct 2000
Abstract excerpt
Rous sarcoma virus (RSV), a simple retrovirus, needs to export unspliced viral RNA from the nucleus to the cytoplasm, circumventing the host cell restriction on cytoplasmic expression of intron-containing RNA. The cytoplasmic accumulation of full-length viral RNA is promoted by two cis-acting direct repeat (DR) elements that flank the src gene; at least one copy of the DR sequence is necessary for viral...
