Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

The SARS-CoV-2 nucleocapsid protein is dynamic, disordered, and phase separates with RNA

Nature Communications, 2021
SARS-CoV-2 nucleocapsid (N) protein is responsible for viral genome packaging. Here the authors employ single-molecule spectroscopy with all-atom simulations to provide the molecular details of N protein and show that it undergoes phase separation with ...

Multiplexed Detection of Respiratory Viruses Using Surface Plasmon Resonance Spectroscopy With Ultrathin Carbon Nanomembranes

Advanced Healthcare Materials, EarlyView.
An ultrathin azide‐functionalized carbon nanomembrane (N3‐CNM) provides a versatile biointerface for antibody immobilization on gold SPR sensors. Integrated with a multichannel SPR platform, the functionalized surface enables label‐free, simultaneous detection of SARS‐CoV‐2, Influenza A, and RSV antigens, demonstrating the potential of CNM‐based ...

Roles of Phosphorylation of the Nucleocapsid Protein of Mumps Virus in Regulating Viral RNA Transcription and Replication [PDF]

Journal of Virology, 2015
ABSTRACT Mumps virus (MuV) is a paramyxovirus with a negative-sense nonsegmented RNA genome. The viral RNA genome is encapsidated by the nucleocapsid protein (NP) to form the ribonucleoprotein (RNP), which serves as a template for transcription and replication.

Viable porcine arteriviruses with deletions proximal to the 3 ' end of the genome [PDF]

, 2001
In order to obtain attenuated live vaccine candidates of porcine reproductive and respiratory syndrome virus (PRRSV), a series of deletions was introduced at the 3′ end of the viral genome using an infectious cDNA clone of the Lelystad virus isolate. RNA

Generation and characterization of a recombinant Rift Valley fever virus expressing a V5 epitope-tagged RNA-dependent RNA polymerase [PDF]

, 2011
The viral RNA-dependent RNA polymerase (RdRp; L protein) of Rift Valley fever virus (RVFV; family Bunyaviridae) is a 238 kDa protein that is crucial for the life cycle of the virus, as it catalyses both transcription of viral mRNAs and replication of the

An Engineered HR1‐Stem Helix‐HR2 Trimeric Platform for Developing Broad‐Spectrum Coronavirus Vaccines

Advanced Science, EarlyView.
Sun et al. report a self‐assembling trimeric subunit vaccine platform termed RHS, which integrates the JN.1 receptor‐binding domain (RBD) with the heptad repeat 1 (HR1), stem helix (SH), and heptad repeat 2 (HR2) regions. The SARS‐CoV‐2 RHS vaccine elicits variant‐reactive RBD‐specific antibodies and cross‐reactive SH‐specific antibodies against ...

Improved control of SARS-CoV-2 by treatment with nucleocapsid-specific monoclonal antibody [PDF]

, 2022
The SARS-CoV-2 spike protein is the main antigen in all approved COVID-19 vaccines and is also the only target for monoclonal antibody therapies. Immune responses to other viral antigens are generated after SARS-CoV-2 infection, but their contribution to

Dose absorption of Omicron variant SARS-CoV-2 by electron radiation: Using Geant4-DNA toolkit

Nuclear Engineering and Technology
In this research, the Omicron variant of the SARS-CoV-2 virus was simulated and exposed to electron radiation with up to 20 keV energy. Absorbed energy was measured for spike protein, nucleocapsid protein, and envelope of the virus.
