Abstract

Analysis of promoter mutants and hybrids in permanently transformed murine L cells reveals several regulatory DNA sequence elements in the 5' flanking region of the human interferon-beta gene, which together constitute the inducible promoter. The elements consist almost exclusively of purine runs in the region -111 to -1. Deletion of single elements reduces the expression capacity drastically, whereas duplication leads to a synergism of inducible expression. These elements act together in a cooperative way to achieve high inducibility. Natural and mutant promoter fragments containing these elements impose inducibility on a heterologous promoter. However, typical enhancer activity in this system is not observed.
