Abstract

We have used a DNAase I genomic footprinting procedure to detect interactions between cellular factors and the regulatory sequences of the human β-interferon gene. Prior to induction with poly(I)-poly(C), factors that bind to DNA are detected in one region located between −94 and −167 from the mRNA cap site, and in another region located between −68 and −38. After induction these factors dissociate and another factor binds to a region located between −77 and −64. Correlation of these footprints with the effects of deletions in the regulatory region of the β-interferon gene (accompanying paper) suggest that the factors that bind prior to induction are repressor molecules, while the component that binds after induction is a transcription factor. Dissociation of the repressor molecules from the DNA after induction may allow the transcription factor to bind to and activate the β-interferon promoter. Thus, the β-interferon gene may be controlled by a negative regulatory mechanism.
