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, None) , ( protein: Egr-1, None) , ( protein: Egr-1, None) , ( DNA: IL-2Rbeta DNA binding motif, None) , ( protein: PIF, None) , ( protein: Egr-1, None) , ( DNA: Egr-1 binding site, None)
