Eukaryotic transcriptional regulatory signals, defined as core and activator promoter elements, have yet to be identified in the earliest diverging group of eukaryotes, the primitive protozoans, which include the Trypanosomatidae family of parasites. The divergence within this family is highlighted by the apparent absence of the "universal" transcription(More)
Typical general transcription factors, such as TATA binding protein and TFII B, have not yet been identified in any member of the Trypanosomatidae family of parasitic protozoa. Interestingly, mRNA coding genes do not appear to have discrete transcriptional start sites, although in most cases they require an RNA polymerase that has the biochemical properties(More)
The simian virus 40 large T antigen is a promiscuous transcriptional activator of many viral and cellular promoters. We show that the promoter structure necessary for T antigen-mediated transcriptional activation is very simple. A TATA or initiator element is required, in addition to an upstream factor-binding site, which can be quite variable. We found(More)
The late promoter of simian virus 40 is transcriptionally activated, in trans, by large T antigen, the primary viral early gene product. Although large T antigen is a well-characterized DNA-binding protein, a variety of data suggest that its trans-activation function does not require direct interaction with DNA. We demonstrate that defined late promoter(More)
Glucocorticoids exert their action on gene expression through activation of cytoplasmic glucocorticoid receptors (GRs) that bind to glucocorticoid response elements (GREs). The consensus GRE consists of two half sites (underlined), AGAACANNNTGTTCT. We have recently cloned the entire human elastin gene. Nucleotide sequencing of the promoter region disclosed(More)
