The HSV-1 ICP22 protein selectively impairs histone repositioning upon Pol II transcription downstream of genes (Omni-ATAC-seq I)

T-HF cells were grown either in the presence or absence of DOX. Upon DOX exposure, cells expressed either HA-ICP22 or HA-ICP22 and V5-ICP27. T-HF HA-ICP22 cells were treated with salt stress for 2 hours before proceeding with Omni-ATAC-seq. OMNI-ATAC-seq was conducted for the KOS1.1 strain and compared to a full US1 deletion mutant. T-HF cells were grown either in the presence or absence of DOX (5 µg/ml) for 48 h. Upon DOX exposure, cells expressed either HA-ICP22 or HA-ICP22 and V5-ICP27. T-HF HA-ICP22 cells were treated with 80 mM KCl (salt stress) for 2 hours before proceeding with Omni-ATAC-seq. HFFF cells were infected for 8h under PAA treatment with MOI 10 of KOS1.1 and an isogenic US1 deletion mutant.
