Multifaceted contributions of Dicer2 to arbovirus transmission by Aedes aegypti

Cell Reports, 2023
Summary: Arthropod-borne viruses (arboviruses) transmitted by Aedes aegypti mosquitoes are an increasing threat to global health. The small interfering RNA (siRNA) pathway is considered the main antiviral immune pathway of insects, but its effective ...

Possible roles of endogenous RNA virus elements in RNA virus infection

Uirusu, 2016
Endogenous bornavirus-like elements (EBLs) are ancient bornavirus-derived sequence in the genomes of eukaryotes. Expression profile of EBLs suggests that, although most of the EBLs in mammalian genomes have lost their coding potential, many of them are transcribed in a cell-type specific or ubiquitous manner. This observation leads us to speculate that

Dual function of the nuclear export signal of the Borna disease virus nucleoprotein in nuclear export activity and binding to viral phosphoprotein

Virology Journal, 2017
Background Borna disease virus (BoDV), which has a negative-sense, single-stranded RNA genome, causes persistent infection in the cell nucleus. The nuclear export signal (NES) of the viral nucleoprotein (N) consisting of leucine at positions 128 and 131 ...

Evolutionary Selection of the Nuclear Localization Signal in the Viral Nucleoprotein Leads to Host Adaptation of the Genus Orthobornavirus

Viruses, 2020
Adaptation of the viral life cycle to host cells is necessary for efficient viral infection and replication. This evolutionary process has contributed to the mechanism for determining the host range of viruses.

Detection of genome-scale ordered RNA structure (GORS) in genomes of positive-stranded RNA viruses:Implications for virus evolution and host persistence [PDF]

, 2004
Discrete RNA secondary and higher-order structures, typically local in extent, play a fundamental role in RNA virus replication. Using new bioinformatics analysis methods, we have identified genome-scale ordered RNA structure (GORS) in many genera and ...

Riboswitching on RNA virus replication [PDF]

Proceedings of the National Academy of Sciences, 2007
Positive-strand RNA viruses direct different virus-specific processes during their infection of host cells. Fundamental events such as viral RNA genome replication are controlled by viral regulatory RNA elements (REs). Here, we have investigated the possibility of specifically modulating the action of a viral RE using RNA aptamer technology.

A hepatitis C virus cis-acting replication element forms a long-range RNA-RNA interaction with upstream RNA sequences in NS5B [PDF]

, 2008
The genome of hepatitis C virus (HCV) contains cis-acting replication elements (CREs) comprised of RNA stem-loop structures located in both the 5' and 3' non-coding regions (NCR), and in the NS5B coding sequence.

Revisiting and corrections to the annotated SRSF3 (SRp20) gene structure and RefSeq sequences from the human and mouse genomes

Cell Insight, 2023
SRSF3 (SRp20) is the smallest member of the serine/arginine (SR)-rich protein family. We found the annotated human SRSF3 and mouse Srsf3 RefSeq sequences are much larger than the detected SRSF3/Srsf3 RNA size by Northern blot.
