This activation was due to the translocation of p65 and c-Rel NF.kappa B proteins from cytoplasmic stores to the nucleus, where they bound the kappa B sequence of the IL-2R alpha promoter either as p50.p65 or as p50. c-Rel heterodimers.
 p50.p65, c-Rel, NF.kappa B, p50. c-Rel, kappa B sequence, p65, c-Rel, IL-2R alpha promoter
