Genomic footprints across Rp, Zp, and oriLyt of Epstein-Barr virus (EBV) have been conducted in a panel of latently infected B-cell lines. Close protein-base contacts were found about 360 nucleotides upstream of the Zp initiation site. Gel shifts and transient transfection assays indicated that an Sp1-NF1 locus may serve as a repressive transcriptional element against Zp induction from latent EBV genomes.
在一组潜伏感染的B细胞系中,对爱泼斯坦-巴尔病毒(EBV)的Rp、Zp和oriLyt进行了基因组足迹分析。在Zp起始位点上游约360个核苷酸处发现了紧密的蛋白质-碱基接触。凝胶迁移和瞬时转染分析表明,一个Sp1-NF1位点可能作为一个抑制性转录元件,抑制潜伏EBV基因组中Zp的诱导。
