Characterization of the influenza A virus gene pool in avian species in southern China: was H6N1 a derivative or a precursor of H5N1?

abstract：:Rotavirus NSP5 is a nonstructural protein that localizes in cytoplasmic viroplasms of infected cells. NSP5 interacts with NSP2 and undergoes a complex posttranslational hyperphosphorylation, generating species with reduced polyacrylamide gel electrophoresis mobility. This process has been suggested to be due in part t...

abstract：:Bluetongue virus (BTV), a member of the Reoviridae family, is an insect-borne animal pathogen. Virus release from infected cells is predominantly by cell lysis, but some BTV particles are also released from the plasma membrane. The nonstructural protein NS3 has been implicated in this process. Using alternate initiato...
