WebMultiple studies have demonstrated that viral mRNAs are susceptible to HSFs, an effect that is presumably overcome by high-level transcription of lytic mRNAs [13,21,24,25,26]. Thus, HSFs may fine tune expression levels of viral mRNAs and HSF knockout has the potential to disrupt the stoichiometry of viral proteins required for optimal viral ...
