Abstract: We have used transient expression assays to study transcription directed by the human immunodeficiency virus (HIV) type 1 promoter. A plasmid containing an HIV-reporter gene fusion and a simian virus 40 origin of DNA replication was transfected into COS-1 cells in the presence or absence of a Tat expression vector. HIV-promoted RNA was analyzed by in vivo labeling, by RNase protection mapping, and in run-on transcription assays. As observed previously, two populations of HIV RNA accumulate in vivo: short, atte…
