Outline of Final Research Achievements

The genome of HIV-1 always forms dimer in virion. The genome dimerization is believed to have important roles on viral infectivity and/or pathogenicity. Previously I suggested the dimerization signal region RNA (DLS) of HIV-1 forms pseudoknot-like structure. In this project, I explored a precise functional structures around the pseudoknot, such as SL1 and primer binding site applying virological/molecular biological approach. In addition, I focused on the p1 region, which is important for viral maturation process and examined its roles on viral infectivity and genome packaging.
