Resumen:
RNA polymerase pausing and transcriptional antitermination regulates
gene activity in several systems. In arenavirus infected cells the
switch from transcription to replication is subjected to a
hairpin-dependent termination and requires protein synthesis to bypass
this signal. The transcriptional antitermination control by Junín virus
nucleocapsid protein N, has been demonstrated in vivo by infecting
BHK-21 cells expressing this viral protein in the presence of
translation inhibitors. This is the first demonstration in vivo of a
transcriptional antitermination control in arenavirus-infected cells.
