Controlled transcription of a human alpha-interferon gene introduced into mouse L cells. Our data suggest that IRF-1 participates in the transient formation of an induction-specific complex es with the regulatory elements. A nucleotide promoter segment from an IFN-alpha gene renders an unrelated promoter inducible by virus.
