Structural insights into the binding modes of viral RNA-dependent RNA polymerases using a function-site interaction fingerprint method for RNA virus drug discovery [PDF]

open access: yes, 2020
The COVID-19 pandemic speaks to the need for drugs that are not only effective but also remain so given the mutation rate of COVID-19. To this end, we describe a strategy to design potential drugs that target RNA-dependent RNA polymerase (RDRP), a common

Enterovirus infections in children

open access: yesPediatric Investigation, EarlyView.
Enteroviruses (EVs) are major pathogens causing a wide spectrum of diseases in children worldwide. This review summarizes the epidemiology, virology, viral replication, and virus‐host interactions of EVs. It also highlights current advances in clinical diagnosis, antiviral therapies, and vaccine development, providing insights into future strategies ...

Analyses of the archaeal transcription cycle reveal a mosaic of eukaryotic RNA polymerase II and III-like features [PDF]

open access: yes, 2009
Novel mechanistic properties of the archaeal transcription system that reveal similarities especially to the eukaryotic RNA polymerase II and III systems were presented in thesis.

Iflaviruses in arthropods: when small is mighty

open access: yesInsect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Definition of the minimal viral components required for the initiation of unprimed RNA synthesis by influenza virus RNA polymerase [PDF]

open access: yes, 2002
The first 11 nt at the 5' end of influenza virus genomic RNA were shown to be both necessary and sufficient for specific binding by the influenza virus polymerase.

The RNA Polymerase II-associated factor 1 complex represses small-RNA-mediated heterochromatin formation and gene silencing [PDF]

open access: yes, 2015
RNAi interference (RNAi) is a highly conserved regulatory mechanism employed by almost all Eukaryotes. With RNAi organisms can modulate the expression of endogenous genes and protect the integrity and identity of their genomes.

Origin and Evolution of RNA-Dependent RNA Polymerase

open access: yesFrontiers in Genetics, 2017
RNA-dependent RNA polymerases (RdRp) are very ancient enzymes and are essential for all viruses with RNA genomes. We reconstruct the origin and evolution of this polymerase since the initial stages of the origin of life. The origin of the RdRp was traced

In Situ Hybridization and RT‐PCR Detection of Nervous Necrosis Virus in Fourfinger Threadfin, Eleutheronema tetradactylum, in Taiwan

open access: yesJournal of Fish Diseases, Volume 49, Issue 10, October 2026.
ABSTRACT Between April and July 2020, suspected outbreaks of nervous necrosis virus (NNV) infection were observed in fourfinger threadfin (Eleutheronema tetradactylum) fingerling hatcheries in Pingtung County, southern Taiwan. Affected fish exhibited spiral swimming behaviour and abdominal distension, resulting in mortality rates between 50% and 100 ...

Structure of the Complete RNA Polymerase II Elongation Complex and its Interaction with the Elongation Factor TFIIS [PDF]

open access: yes, 2005
This thesis describes crystal structures of complete, 12-subunit yeast RNA polymerase II (Pol II) in complex with a synthetic transcription bubble and product RNA, with an NTP substrate analogue, and in complex with the transcription elongation factor ...

Diverging affinity of tospovirus RNA silencing suppressor proteins, NSs, for various RNA duplex molecules [PDF]

open access: yes, 2010
The tospovirus NSs protein was previously shown to suppress the antiviral RNA silencing mechanism in plants. Here the biochemical analysis of NSs proteins from different tospoviruses, using purified NSs or NSs containing cell extracts, is described.
