In the transient-transfection assay , ICP0 , but not ICP4 , activated the HIV-1 long terminal repeat promoter region and the effect of ICP0 was greatly enhanced in the presence of the NF-kappa B binding proteins , suggesting that induction of the HIV-1 provirus involves cooperation between the HSV-1-activated cellular factor , NF-kappa B , and the virus-encoded transactivator , ICP0 .
