The region which induced these inductions was identified as being confined to 40 nucleotides 5' to the major transcriptional initiation site by testing a series of clones with truncated promoter of IRF-2 .
 DNA: major transcriptional initiation site; DNA: truncated promoter; protein: IRF-2; DNA: 40 nucleotides 5'
