ABSTRACT
Internal Ribosome Entry Site (IRES) sequences have been widely used to link the expression of two independent proteins on the same mRNA transcript. Genes encoding fluorescent proteins or drug-resistance enzymes are usually placed downstream of IRES, serving as expression indicators or selection markers. In biological applications where the upstream gene-of-interest is to be expressed at extremely high levels, it is often desirable to purposely reduce IRES downstream gene expression to economize the cellular resources and/or to generate more stringent selection pressure. Here we describe a miniature IRES mutant sequence (IRESmut3) with dramatically diminished co-translational efficiency to fulfill these purposes.
