The gateway pDEST17 expression vector encodes a −1 ribosomal frameshifting sequence
The attB1 site in the Gateway (Invitrogen) bacterial expression vector pDEST17, necessary for in vitro site-specific recombination, contains the sequence AAA-AAA. The sequence A-AAA-AAG within the Escherichia coli dnaX gene is recognized as 'slippery' and promotes -1 translational frameshifting. We show here, by expressing in E. coli several plant cDNAs with and without single nucleotide deleti...
متن کاملExpression strategies of the yeast retrotransposon Ty: a short sequence directs ribosomal frameshifting.
The Ty element of yeast is a member of a class of eukaryotic transposons which bear a striking resemblance to retroviral proviruses in their structure and expression strategies (1,2). A direct comparison can be drawn between the production of a fusion protein encoded by Ty, resulting from a frameshift event which fuses two out-of-phase open reading frames TYA and TYB, and the production of Pr18...
متن کاملRibosomal frameshifting used in influenza A virus expression occurs within the sequence UCC_UUU_CGU and is in the +1 direction
Programmed ribosomal frameshifting is used in the expression of many virus genes and some cellular genes. In eukaryotic systems, the most well-characterized mechanism involves -1 tandem tRNA slippage on an X_XXY_YYZ motif. By contrast, the mechanisms involved in programmed +1 (or -2) slippage are more varied and often poorly characterized. Recently, a novel gene, PA-X, was discovered in influen...

متن کاملA dynamical model of programmed -1 ribosomal frameshifting.
Programmed -1 ribosomal frameshifting is the most widely used translational recoding mechanism of RNA viruses. How the frameshifting occurs at the slippery sequence on the presence of a downstream mRNA pseudoknot has not been fully understood. Here, we present systematical analysis of the -1 frameshifting that can occur during every transition step in elongation phase of protein synthesis by Es...
