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, None) , ( DNA: GASd/EBSd element, None) , ( protein: Elf-1, None) , ( protein: T-cell-specific Elf-1 factor, None) , ( protein: transcriptional repressor, None) , ( protein: IL-2R alpha, None)
