Topology 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 کاملDiscovery of Dengue Virus NS4B Inhibitors.
The four serotypes of dengue virus (DENV-1 to -4) represent the most prevalent mosquito-borne viral pathogens in humans. No clinically approved vaccine or antiviral is currently available for DENV. Here we report a spiropyrazolopyridone compound that potently inhibits DENV both in vitro and in vivo. The inhibitor was identified through screening of a 1.8-million-compound library by using a DENV...
متن کاملMembrane topology and function of dengue virus NS2A protein.
Flavivirus nonstructural protein 2A (NS2A) is a component of the viral replication complex that functions in virion assembly and antagonizes the host immune response. Although flavivirus NS2A is known to associate with the endoplasmic reticulum (ER) membrane, the detailed topology of this protein has not been determined. Here we report the first topology model of flavivirus NS2A on the ER membr...
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 کاملN- and C-terminal amino acids of saliva parotin A.
During the course of an investigation into the biological activities and chemical properties of saliva parotin A it became necessary to study the chemical structure of this protein. Previous workers have reported that the molecular weight of saliva parotin A prepared from human saliva is 15,900 (Ito, Y. 1960). Proline, threonine, aspartic acid, and gluta mic acid are contained in saliva parotin...
