IgE germline promoter reporter gene constructs carrying point mutations in the NF kappa B2 site were largely unresponsive to IL-4 stimulation in transient transfection experiments, while plasmids with similar mutations in the NF kappa B1 site responded to cytokine stimulation better than the wild-type promoter .
