The Tat protein of human immunodeficiency virus type 1 (HIV-1) trans-activates HIV-1 transcription by functionally interacting with a number of cellular proteins, among which the Sp1 transcription factor. We recently demonstrated that Tat does not directly interact with Sp1 either in vitro or in vivo, and we suggested that other protein(s) could indirectly(More)
The role of Sp1 in regulating the trans-activating activity of the human immunodeficiency virus type 1 (HIV-1) Tat protein has not yet been clearly defined. In fact, studies on the physical and functional interaction between Sp1 and Tat have yielded contradictory results. Here we investigated whether a physical interaction between Sp1 and Tat indeed occurs,(More)
