Polygenic viral factors enable efficient mosquito-borne transmission of African Zika virus

open access: yesNature Communications
Zika virus (ZIKV) is a mosquito-borne orthoflavivirus primarily transmitted among humans by Aedes aegypti. Over the past two decades, it has caused significant outbreaks associated with birth defects and neurological disorders.

A Genetic Locus Regulates the Expression of Tissue-Specific mRNAs from Multiple Transcription Units [PDF]

open access: yes, 1982
129 GIX- mice, unlike animals of the congeneic partner strain GIX+, do not express significant amounts of the retroviral antigens gp70 and p30. Evidence is presented indicating that the GIX phenotype is specified by a distinct regulatory gene acting on ...

Initiation of viral RNA-dependent RNA polymerization

open access: yesJournal of General Virology, 2004
This review summarizes the combined insights from recent structural and functional studies of viral RNA-dependent RNA polymerases (RdRPs) with the primary focus on the mechanisms of initiation of RNA synthesis. Replication of RNA viruses has traditionally been approached using a combination of biochemical and genetic methods.

Multiple ETS family transcription factors bind mutant p53 via distinct interaction regions

open access: yesFEBS Letters, EarlyView.
Mutant p53 gain‐of‐function is thought to be mediated by interaction with other transcription factors. We identify multiple ETS transcription factors that can bind mutant p53 and found that this interaction can be promoted by a PXXPP motif. ETS proteins that strongly bound mutant p53 were upregulated in ovarian cancer compared to ETS proteins that ...

Radial distribution of RNA genome packaged inside spherical viruses

open access: yes, 2008
The problem of RNA genomes packaged inside spherical viruses is studied. The viral capsid is modeled as a hollowed sphere. The attraction between RNA molecules and the inner viral capsid is assumed to be non-specific and occurs at the inner capsid ...

The respiratory syncytial virus nucleoprotein–RNA complex forms a left-handed helical nucleocapsid [PDF]

open access: yes, 2013
Respiratory Syncytial Virus (RSV) is an important human pathogen. Its nucleocapsid (NC), which comprises the negative sense RNA viral genome coated by the viral nucleoprotein N, is a critical assembly that serves as template for both mRNA synthesis and ...

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

open access: yesMolecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

N 6-methyladenosine RNA modification suppresses antiviral innate sensing pathways via reshaping double-stranded RNA

open access: yesNature Communications, 2021
N6-methyladenosine (m6A) RNA modification regulates RNA metabolism, and has been implicated in immune regulation. Here, the authors show that the m6A methyltransferase, METTL3, translocates into the cytoplasm to increase viral RNA m6A modification ...

Favipiravir (T-705), a broad spectrum inhibitor of viral RNA polymerase

open access: yesProceedings of the Japan Academy. Series B, Physical and biological sciences, 2017
Favipiravir (T-705; 6-fluoro-3-hydroxy-2-pyrazinecarboxamide) is an anti-viral agent that selectively and potently inhibits the RNA-dependent RNA polymerase (RdRp) of RNA viruses.

A comparison of viral RNA-dependent RNA polymerases

open access: yesCurrent Opinion in Structural Biology, 2006
Genome replication in picornaviruses is catalyzed by a virally encoded RNA-dependent RNA polymerase, termed 3D. These viruses also use a small protein primer, named VPg, to initiate RNA replication. The recent explosion of structural information on picornaviral 3D polymerases has provided insights into the initiation of RNA synthesis and chain ...
