Abstract

We analyzed the 5' transcription control sequences of the human CD4 gene. We located the transcription initiation site and showed that the CD4 core promoter (positions -40 to +16) lacks a classical "TATA" or initiator positioning consensus sequence but directs precise and efficient transcription when coupled to the ubiquitously active simian virus 40 enhancer. The transcriptional activity of the CD4 gene promoter correlated with CD4 expression in various cell types. Interestingly, the CD4 core promoter also displayed a tissue-specific transcriptional activity. Within this fragment, three nucleic acid sequences are completely conserved in the murine CD4 gene. One of these sequences contains a perfect ETS consensus sequence. Another ETS consensus sequence is located 1060 nt upstream. Electrophoretic-mobility-shift assays showed that the core promoter ETS motif binds an Ets-related protein specifically expressed at high levels in CD4+ cells. Moreover, in CD4- cells, overexpression of Ets-1 or Ets-2 efficiently and specifically activated transcription from the CD4 promoter and core promoter. These data indicate that Ets transcription factors play a central role in controlling CD4 gene expression, by binding to both a classical remote site and an unusual proximal activator sequence.
