KSHV ORF57, a Protein of Many Faces

Viruses, 2015
Kaposi’s sarcoma-associated herpesvirus (KSHV) ORF57 protein (also known as mRNA transcript accumulation (Mta)) is a potent posttranscriptional regulator essential for the efficient expression of KSHV lytic genes and productive KSHV replication.

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

, 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.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Antagonistic activity against innate immunity determines virulence in mammalian bornaviruses

npj Viruses
Variegated squirrel bornavirus 1 (VSBV-1) is a lethal emerging disease that has been discovered in privately owned and zoo squirrels, but its pathogenicity as a zoonotic pathogen remains uncertain.

Reduction of HIV-1 RNA levels with therapy to suppress herpes simplex virus. [PDF]

, 2007
BACKGROUND: Epidemiologic data suggest that infection with herpes simplex virus type 2 (HSV-2) is associated with increased genital shedding of human immunodeficiency virus type 1 (HIV-1) RNA and HIV-1 transmissibility. METHODS: We conducted a randomized,

RNA of mouse hepatitis virus [PDF]

Journal of Virology, 1978
The RNA of mouse hepatitis virus, a coronavirus, was isolated from the virus released early in the infection and analyzed by sucrose gradient sedimentation and electrophoresis. It was found to consist of a piece of single-stranded RNA of about 60S. Its molecular weight was estimated to be 5.4 X 10(6) by electrophoresis in methylmercury-agarose gels. At

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Development of an RNA Virus-Based Episomal Vector Capable of Switching Transgene Expression

Frontiers in Microbiology, 2019
Viral vectors are efficient gene delivery systems, although most of these vectors still present limitations to their practical use, such as achieving only transient transgene expression and a risk of insertional mutations.

Nucleocapsid protein structures from orthobunyaviruses reveal insight into ribonucleoprotein architecture and RNA polymerization [PDF]

, 2013
All orthobunyaviruses possess three genome segments of single-stranded negative sense RNA that are encapsidated with the virus-encoded nucleocapsid (N) protein to form a ribonucleoprotein (RNP) complex, which is uncharacterized at high resolution.
