Genetic analysis of Murine hepatitis virus nsp4 in virus replication.
Coronavirus replicase polyproteins are translated from the genomic positive-strand RNA and are proteolytically processed by three viral proteases to yield 16 mature nonstructural proteins (nsp1 to nsp16). nsp4 contains four predicted transmembrane-spanning regions (TM1, -2, -3, and -4), demonstrates characteristics of an integral membrane protein, and is thought to be essential for the formatio...
متن کاملMutations across murine hepatitis virus nsp4 alter virus fitness and membrane modifications.
UNLABELLED A common feature of infection by positive-sense RNA virus is the modification of host cell cytoplasmic membranes that serve as sites of viral RNA synthesis. Coronaviruses induce double-membrane vesicles (DMVs), but the role of DMVs in replication and virus fitness remains unclear. Coronaviruses encode 16 nonstructural proteins (nsps), three of which, nsp3, nsp4, and nsp6, are necessa...
متن کاملGenetic analysis of murine hepatitis virus non-structural protein 16.
MHV-Wüts18 is an RNA-negative, temperature-sensitive mutant of mouse coronavirus, strain murine hepatitis virus (MHV)-A59. We have previously identified the putative causal mutation of MHV-Wüts18 as a C to U transition at codon 2446 in ORF1b, which results in a substitution of proline 12 with serine in non-structural protein 16. Here, we have used a vaccinia virus-based reverse genetic system t...
متن کاملThe Absence of Hepatitis C Virus Infection Among Patients with Hepatitis B virus in Mashhad, Iran
Background and Aims: Many studies have provided evidence for the role of hepatitis B and C viruses in the development of liver cancer. Although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with HBV and HCV. This study was performed to determine the frequency of HBV/HCV-coinfection in Mashhad, North-East of Iran. Mat...
