Our data demonstrate a major role of the GASd/EBSd element in IL-2R alpha regulation and suggest that the T-cell-specific Elf-1 factor can serve as a transcriptional repressor .
 DNA: GASd/EBSd; DNA: GASd/EBSd element; protein: Elf-1; protein: T-cell-specific Elf-1 factor; protein: transcriptional repressor; protein: IL-2R alpha
