Flock house virus: down-regulation of subgenomic RNA3 synthesis does not involve coat protein and is targeted to synthesis of its positive strand.

abstract：:Two mutant strains (vi12 and vi13) of herpes simplex virus that contain insertion mutations in the sequences that encode the DNA-binding domain of viral regulatory protein ICP4 were generated. Both mutations disrupted specific DNA binding and resulted in transcriptionally inactive molecules; however, the ability of th...
