In this paper, we demonstrate that PIF is Egr-1 based on its recognition by anti- Egr-1 antisera in gel mobility shift assays , even though the IL-2Rbeta DNA binding motif differed substantially from the canonical Egr-1 binding site .
 protein: IL-2Rbeta; protein: Egr-1; protein: Egr-1; DNA: IL-2Rbeta DNA binding motif; protein: PIF; protein: Egr-1; DNA: Egr-1 binding site
