| Outline of Final Research Achievements |
GAPDH, a host protein, suppresses the packaging of tRNALys3, which is required for effective viral reverse transcription as a primer. Here, I investigated the mechanism of tRNALys3-packaging suppression by GAPDH. As results, GAPDH interacts with both matrix region and capsid region of viral precursor protein. Interestingly, GAPDH oligomerization prevents tRNALys3 packaging into virions. These findings indicate that utilization of the role of GAPDH in tRNALys3 packaging is effective for preventing initiation of HIV reverse transcription.
