Enhanced NF-kappa B binding activity is followed by functional activation in that inducibility of the IL-2 receptor alpha chain is mediated by enhanced NF-kappa B binding and that a heterologous promoter containing the NF-kappa B consensus sequence ( -291 to -245 ) of the IL-2 receptor alpha chain gene is activated.
