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, we quantified reverse-transcription intermediates in HIV-1–infected T cells to…

Extended Interactions between HIV-1 Viral RNA and tRNALys3 Are Important to Maintain Viral RNA Integrity

The data revealed that the additional intermolecular interaction between tRNALys3 and vRNA is likely a conserved mechanism among various HIV-1 strains and protects the vRNA from RNaseH degradation in mature virions.

The three-way junction structure of the HIV-1 PBS-segment binds host enzyme important for viral infectivity

Mutagenesis and phylogenetic analyses provide evidence for conservation of the PBS-segment three-way junction structure that is preferentially bound by RHA in support of efficient reverse transcription, the hallmark step of HIV-1 replication.

HIV-1 hypermethylated guanosine cap licenses specialized translation unaffected by mTOR

The down-regulation of the trimethylguanosine synthetase-1–reduced HIV-1 infectivity and virion protein synthesis by several orders of magnitude and identified mutually exclusive translation pathways and the calibration of virion structural/accessory protein synthesis with de novo synthesis of the viral regulatory proteins.

The mRNA encoding the JUND tumor suppressor detains nuclear RNA-binding proteins to assemble polysomes that are unaffected by mTOR

A noncanonical cap-binding complex consisting of NCBP1/NCBP3 and RHA substitutes for the eukaryotic translation initiation factors 4E and 4G and activates mTOR-independent translation of the mRNA encoding the tumor suppressor JUND.

A New Approach to 3D Modeling of Inhomogeneous Populations of Viral Regulatory RNA

SimRNA and the workflow developed herein provides viable options to predict 3D conformations of inhomogeneous populations of large RNAs that have been intractable to conventional ensemble methods.

Phosphorylation Targets of DNA-PK and Their Role in HIV-1 Replication

It was showed that the kinase activity of DNA-PK is essential for post-integrational DNA repair in the case of HIV-1 infection and their participation in the HIV- 1 life cycle was demonstrated.

In silico model of infection of a CD4(+) T-cell by a human immunodeficiency type 1 virus, and a mini-review on its molecular pathophysiology

The HIV virus can promote a novel differentiated state in the T- cell, which can give account for clinical features seen in patients and the general T-cell count decline, and their log-rank distributions can be modeled as discrete beta generalized distributions (DGBD).

Decoding the vital segments in human ATP-dependent RNA helicase

It is shown that only 9 loci among the 42 active-site residues are conserved with limited structural fluctuation from the wild type structure, and data shows limited degree of conserved sequence segments with topological flexibility unlike in other subfamily members of the protein.

RNA helicase A modulates translation of HIV-1 and infectivity of progeny virions

The identification of RHA-dependent PCE activity in cellular junD RNA and in six of seven genera of Retroviridae suggests conservation of this translational control mechanism among vertebrates, and convergent evolution of Retoviridae to utilize this host mechanism.

Association of RNA Helicase A with Human Immunodeficiency Virus Type 1 Particles*

RHA represents the first example of cellular RNA helicases that participate in HIV-1 particle production and promote viral reverse transcription.

Coordinate roles of Gag and RNA helicase A in promoting the annealing of formula to HIV-1 RNA.

Since RHA has been reported to promote the translation of unspliced viral RNA to Gag protein, the observations suggest that the conformational change in viralRNA induced by RHA and newly produced Gag may help facilitate the switch in viral RNA from a translational mode to one facilitating tRNA(3)(Lys) annealing.

Coordinate Roles of Gag and RNA Helicase A in Promoting the Annealing of tRNA3 Lys to HIV-1 RNA

Since RHA has been reported to promote the translation of unspliced viral RNA to Gag protein, the observations suggest that the conformational change in viralRNA induced by RHA and newly produced Gag may help facilitate the switch in viral RNA from a translational mode to one facilitating tRNA3 Lys annealing.

Translation Is Not Required To Generate Virion Precursor RNA in Human Immunodeficiency Virus Type 1-Infected T Cells

Results from this data contrast with results from the HIV-2 and murine leukemia virus systems and indicate that HIV-1 unspliced RNA constitutes a single functional pool that can function interchangeably as mRNA and as vpRNA.

Human immunodeficiency virus Type 1 nucleocapsid protein (NCp7) directs specific initiation of minus-strand DNA synthesis primed by human tRNA(Lys3) in vitro: studies of viral RNA molecules mutated in regions that flank the primer binding site

Retroviral reverse transcription starts near the 5' end of unspliced viral RNA at a sequence called the primer binding site (PBS), where the tRNA primer anneals to the RNA template for initiation of DNA synthesis, and NCp7 was found to stimulate synthesis of minus-strand strong-stop DNA [(-)ssDNA], consistent with previous reports.

RNA helicase A interacts with divergent lymphotropic retroviruses and promotes translation of human T-cell leukemia virus type 1

It is concluded that PCE/RHA is an important translation regulatory axis of multiple lymphotropic retroviruses that have evolved a convergent RNA–protein interaction to modulate translation of their highly structured mRNA.

Pausing during Reverse Transcription Increases the Rate of Retroviral Recombination

It is demonstrated that reverse transcriptase pausing, as observed in vitro, directly correlates with recombination during minus-sense DNA synthesis in vivo.
