EMCV IRES
This is an Internal Ribosome Entry Site (IRES) acting in mammalian cells. It allows translation initiation in the middle of an RNA strand which is required for the fuctioning of our replicon as there are multiple protein coding regions separated by structural nucleotide sequences interspersed throuhgout the RNA strand. We chose to investigate two IRES sequences to compare the relative efficiency and determine which was better for incorporation into our system. These were the Encephalomyocarditis virus (EMCV) and the IRES derived from the NF-kappaB repressor factor (NKRF) untranslated region.
IRES' were first discovered in EMCV and polioviruses and the EMCV has been the favoured IRES for use in replicon systems such as Lohmann (1999) and Lee (2005).
