Virion-associated, host-derived DHX9/RNA helicase A enhances the processivity of HIV-1 reverse transcriptase on genomic RNA

Abstract excerpt

DHX9/RNA helicase A (RHA) is a host RNA helicase that participates in many critical steps of the HIV-1 life cycle. It co-assembles with the viral RNA genome into the capsid core. Virions deficient in RHA are less infectious as a result of reduced reverse transcription efficiency, demonstrating that the virion-associated RHA promotes reverse transcription before the virion gains access to the new host's RHA. Here,...
