abstract：BACKGROUND:HIV-1 capsid influences viral uncoating and nuclear import. Some capsid is detected in the nucleus but it is unclear if it has any function. We reported that the antibiotic Coumermycin-A1 (C-A1) inhibits HIV-1 integration and that a capsid mutation confers resistance to C-A1, suggesting that capsid might aff...

abstract：BACKGROUND:Reverse transcription (RT) of HIV and SIV is initiated by the binding of the acceptor stem of tRNALys3 to the primer binding site (PBS) of the viral RNA genome. Previous studies have suggested that this tRNALys3 is not the only molecule capable of priming reverse transcription, and that at least one other ly...
