To dissect the molecular basis for the unusually persistent transcription of the IL-2R alpha gene , we analyzed nuclear NF-kappa B binding to a radiolabeled IL-2R alpha kappa B-specific oligonucleotide probe during the time course of CD2 + CD28 activation .
 ( protein: IL-2R alpha, None) , ( protein: NF-kappa B, None) , ( protein: IL-2R alpha, None) , ( protein: CD28, None) , ( protein: CD2, None) , ( DNA: IL-2R alpha gene, None)
