The ubiquitin-like protein ISG15 and its conjugation to proteins (ISGylation) are strongly induced by type I interferon. Influenza B virus encodes non-structural protein 1 (NS1B) that binds human ISG15 and provides an appropriate model for determining how ISGylation affects virus replication in human cells. Here using a recombinant virus encoding a NS1B protein defective in ISG15 binding, we sh...
Cellular proteins called "restriction factors" can serve as powerful blockades to HIV replication, but the virus possesses elaborate strategies to circumvent these barriers. First, we discuss general hallmarks of a restriction factor. Second, we review how the viral Vif protein protects the viral genome from lethal levels of cDNA deamination by promoting APOBEC3 protein degradation; how the vir...
We have attempted to characterize the molecular defect in a temperature-sensitive mutant of vaccinia virus, ts22, which has an abortive late phenotype. At the nonpermissive temperature, ts22 displays normal viral protein synthesis until 8 h postinfection. Between 8 and 10 h after infection all viral protein synthesis ceases abruptly. Characterization of ts22 revealed that (i) primary transcript...
The paramyxovirus family contains many common human pathogenic viruses, including measles, mumps, the parainfluenza viruses, respiratory syncytial virus, human metapneumovirus, and the zoonotic henipaviruses, Hendra and Nipah. While the expression of a type 1 fusion protein and a type 2 attachment protein is common to all paramyxoviruses, there is considerable variation in viral attachment, the...
Ethanol is highly effective against various enveloped viruses and can disable the virus by disintegrating protective envelope surrounding it. The interactions between coronavirus (E) protein its membrane environment play key roles in stability function of viral envelope. By using molecular dynamics simulation, we explore underlying mechanism ethanol-induced disruption a model and, detail, E-pro...
Background and Aims: Fresh Frozen Plasma (FFP) is one of blood components. The risk of transmission of viruses from blood components regardless selection of blood donors and screening donated blood still remains. There are several methods for viral inactivation. In this study methylene blue (MB) photo inactivation process was used for inactivating viruses. Materials and Methods: In this study M...
Studies of the functional proteins encoded by the poxvirus genome provide information about the composition of the virus as well as individual virus-virus protein and virus-host protein interactions, which provides insight into viral pathogenesis and drug discovery. Widely used proteomic techniques to identify and characterize specific protein-protein interactions include yeast two-hybrid studi...
Globally, over 170 million people (ca. 3% of the World's population) are infected with the hepatitis C virus (HCV), which can cause serious liver diseases such as chronic hepatitis, evolving into subsequent health problems. Driven by the need to detect the presence of HCV, as an essential factor in diagnostic medicine, the monitoring of viral protein has been of great interest in developing sim...
