Spt5 Cooperates with Human Immunodeficiency Virus Type 1 Tat by Preventing Premature RNA Release at Terminator Sequences [PDF]
, 2002 The human immunodeficiency virus type 1 (HIV-1) Tat protein activates transcription elongation by stimulating the Tat-activated kinase (TAK/p-TEFb), a protein kinase composed of CDK9 and its cyclin partner, cyclin T1.

Is RNA-dependent RNA polymerase essential for transposon control? [PDF]
BMC Systems Biology, 2011 Eukaryotes use RNA interference and RNA-based epigenetic regulation to control transposon activity. In the standard pathways of RNA-based transcriptional and post-transcriptional silencing the protein complex RNA-dependent RNA polymerase (RdRP) plays a crucial role. However, alternative pathways that bypass RdRP have recently been described.

RNA-dependent RNA Polymerase Assay for Hepatitis E Virus
Bio-Protocol, 2017 RNA-dependent RNA polymerase (RdRp) is essential for the replication of viral RNA for RNA viruses. It synthesizes the complementary strand of viral genomic RNA, which is used subsequently as a template to generate more copies of viral genome.

Stochastic resetting in backtrack recovery by RNA polymerases [PDF]
Phys. Rev. E 93, 062411 (2016), 2016 Transcription is a key process in gene expression, in which RNA polymerases produce a complementary RNA copy from a DNA template. RNA polymerization is frequently interrupted by backtracking, a process in which polymerases perform a random walk along the DNA template.

Activation mechanism of a noncanonical RNA-dependent RNA polymerase [PDF]
Proceedings of the National Academy of Sciences, 2007 Two lineages of viral RNA-dependent RNA polymerases (RDRPs) differing in the organization (canonical vs. noncanonical) of the palm subdomain have been identified. Phylogenetic analyses indicate that both lineages diverged at a very early stage of the evolution of the enzyme [Gorbalenya AE, Pringle FM, Zeddam JL, Luke BT, Cameron CE ...

In vitro RNA-dependent RNA Polymerase Assay Using Arabidopsis RDR6
Bio-Protocol, 2018 RNA-dependent RNA polymerases (RdRPs) in eukaryotes convert single-stranded RNAs into double-stranded RNAs, thereby amplifying small interfering RNAs that play crucial roles in the regulation of development, maintenance of genome integrity and antiviral ...
