Internal translation initiation on the foot‐and‐mouth disease virus IRES is affected by ribosomal stalk conformation
Copyright policy )Internal translation initiation on the foot‐and‐mouth disease virus IRES is affected by ribosomal stalk conformation
A human cell line, in which expression of the ribosomal stalk proteins P1 and P2 has been suppressed by RNAi technology, has been used to test how the loss of these proteins affects IRES‐dependent translation. Foot‐and‐mouth disease virus (FMDV) IRES‐dependent translation from a bicistronic construct is about three fold higher in the P1/P2‐depleted cells than in control cells in the presence of Lb protease. By contrast, no effect on Hepatitis C virus (HCV) IRES translation was observed. These results emphasize the functional heterogeneity of the IRES and they highlight a functional connection between the ribosomal stalk and picornavirus IRES‐dependent translation.
