The results of this study suggest that the NFAT ( -276 to -261 ), the distal octamer ( -256 to -248 ) and the proximal octamer ( -75 to -66 ) sites not only act as enhancers of IL-2 gene transcription in the presence of cellular stimulation , but also have a silencing effect on IL-2 gene expression in resting cells.
