An "integrated model" of programmed ribosomal frameshifting.
Many viral mRNAs, including those of HIV-1, can make translating ribosomes change reading frame. Altering the efficiencies of programmed ribosomal frameshift (PRF) inhibits viral propagation. As a new target for potential antiviral agents, it is therefore important to understand how PRF is controlled. Incorporation of the current models describing PRF into the context of the translation elongation cycle leads us to propose an 'integrated model' of PRF both as a guide towards further characterization of PRF at the molecular and biochemical levels, and for the identification of new targets for antiviral therapeutics.
