Dimerization of flavivirus NS4B protein.
UNLABELLED Flavivirus replication is mediated by a complex machinery that consists of viral enzymes, nonenzymatic viral proteins, and host factors. Many of the nonenzymatic viral proteins, such as NS4B, are associated with the endoplasmic reticulum membrane. How these membrane proteins function in viral replication is poorly understood. Here we report a robust method to express and purify dengu...
متن کاملG-protein Coupled Receptor Dimerization
A growing body of evidence suggests that GPCRs exist and function as dimers or higher oligomers. The evidence for GPCR dimerization comes from biochemical, biophysical and functional studies. In addition, researchers have shown the occurrence of heterodimerization between different members of the GPCR family. Two receptors can interact with each other to make a dimer through their extracellular...
متن کاملTopology of the membrane-associated hepatitis C virus protein NS4B.
Hepatitis C virus (HCV) belongs to the Hepacivirus genus in the Flaviviridae family. Among the least known viral proteins in this family is the nonstructural protein NS4B, which has been suggested to be a part of the replication complex. Hydrophobicity plots indicate a common profile among the NS4B proteins from different members of the Flaviviridae family, suggesting a common function. In orde...
متن کاملCharacterization of dengue virus NS4A and NS4B protein interaction.
UNLABELLED Flavivirus replication is mediated by a membrane-associated replication complex where viral membrane proteins NS2A, NS2B, NS4A, and NS4B serve as the scaffold for the replication complex formation. Here, we used dengue virus serotype 2 (DENV-2) as a model to characterize viral NS4A-NS4B interaction. NS4A interacts with NS4B in virus-infected cells and in cells transiently expressing ...
متن کاملMonoclonal antibodies against NS4B protein of japanese encephalitis virus.
Japanese encephalitis (JE) is one of the most prevalent global viral encephalitis viruses. The functions of JEV (virus) NS4B protein are still under investigation. In our study, NS4B was expressed in Escherichia coli and purified by dialysis. Two clones of monoclonal antibodies (MAbs 1B1 and 1C3) against NS4B protein were generated and their characterizations were investigated. IFA, Western blo...
