Genetic Interactions between an Essential 3′ <i>cis</i> -Acting RNA Pseudoknot, Replicase Gene Products, and the Extreme 3′ End of the Mouse Coronavirus Genome
22 Nov 2007
Abstract excerpt
The upstream end of the 3' untranslated region (UTR) of the mouse hepatitis virus genome contains two essential and overlapping RNA secondary structures, a bulged stem-loop and a pseudoknot, which have been proposed to be elements of a molecular switch that is critical for viral RNA synthesis. It has previously been shown that a particular six-base insertion in loop 1 of the pseudoknot is extremely deleterious to...
