The beta-globin dominant control region activates homologous and heterologous promoters in a tissue-specific manner.
We have introduced a human beta-globin minilocus, containing the recently described dominant control region (DCR), the beta-globin or Thy-1 gene, and a thymidine kinase (tk)-neoR gene into erythroid and non-erythroid cells. Analysis of the transcription levels of the genes shows that the DCR directs high levels of human beta-globin, Thy-1 and tk-neo expression independent of integration sites in an erythroid-specific manner. The presence of the DNAasel hypersensitive sites at the 5' end of th...Expand abstract
