20S RNA narnavirus defies the antiviral activity of SKI1/XRN1 in Saccharomyces cerevisiae.

The Journal of biological chemistry - 19 Sept 2008

Esteban Rosa, Vega Lorena, Fujimura Tsutomu

Abstract excerpt

20S RNA virus is a persistent positive strand RNA virus found in Saccharomyces cerevisiae. We previously observed that the virus generated in vivo from a launching vector possessed the correct RNA termini without extra sequences. Here we present evidence that the SKI1/XRN1 5'-exonuclease plays a major role in the elimination of the non-viral upstream sequences from the primary transcripts. The virus, once...
