3) but can downregulate ?sssDNA synthesis during reverse transcription in ERT assays and in cells (10, 14), we examined whether Nullbasic affected DNA synthesis by changing of the composition or the activity of RTCs. non-RTC fractions was observed, indicating that RTC activity from Nullbasic-treated computer virus was impaired. Further analysis showed that viral cores isolated from Nullbasic-treated HIV undergo increased disassembly compared to untreated HIV-1. To our knowledge, this is the first description of an antiviral protein that inhibits reverse transcription by targeting the RTC and affecting core stability. IMPORTANCE HIV-1 contamination is treated by using combinations of antiretroviral drugs that target impartial actions of computer virus replication. A newly described antiviral protein called Nullbasic can also inhibit a combination of different actions in computer virus replication (transcription, reverse transcription,…
