Viruses do not encode their own protein synthesis machinery, but must hijack that of their host cell. Viral mRNAs are vastly outnumbered by cellular mRNAs and therefore many viruses have evolved novel mechanisms to preferentially recruit ribosomes. We are interested in the mechanisms by which retroviruses such as HIV are able to recruit ribosomes to their RNAs at the right time to make the proteins they need for new viral particles.
Due to the compact nature of their genomes, many viruses encode several proteins from one mRNA. We are also interested in the mechanisms that viruses employ to direct translation of different proteins from one RNA molecule.
Understanding of these novel translation mechanisms will not only open up new avenues for treatment of viral infection, but also shed light on cellular protein synthesis. Loss of control of cellular translation has been shown to contribute to diseases such as diabetes and cancer.
