The human cytomegalovirus 80-kilodalton but not the 72-kilodalton immediate-early protein transactivates heterologous promoters in a TATA box-dependent mechanism and interacts directly with TFIID

Abstract excerpt

We have asked how the human cytomegalovirus major immediate-early 1 (IE1) and 2 (IE2) proteins act to transactivate heterologous cellular and viral promoters. Here we show that transactivation of the human immunodeficiency virus long terminal repeat and the 70,000-molecular-weight heat shock protein (hsp70) promoter by IE1 is TATA box independent and that the IE1 protein does not interact directly with the TATA...
