Research Abstract

We developed the unique systems to analyze retroviral genome dimerization or recombination, and performed the experiment to pursue the nature of HIV genome RNA within virus particles. As a result, we suggested the reasonable evidence that genome dimerization directly controls the genome recombination. As this hypothesis has long been proposed but the direct evidence has not been shown, this data has a great significance. We also unveiled the precise relationship between virion maturation and viral genome maturation process. These results are expected to accelerate analyzing of virion maturation mechanism of HIV-1, which has been largely unclear.
