Mutagenesis studies, and the use of a reporter construct containing an enhancerless promoter, indicate that these transcriptional effects are due principally to the 22-bp sequence duplication and the NF kappa B site contained within it.
 protein: NF kappa B; DNA: 22-bp sequence duplication; DNA: NF kappa B site
