Fine mapping by in vivo footprinting demonstrated five transcription factor binding sites that are occupied in both resting and activated peripheral blood T lymphocytes ; these are tandem CRE motifs , a Sp1 site , an overlapping Egr-1/ Sp1 site , and a novel palindromic octamer sequence ( POS ).
 ( cell type: activated peripheral blood T lymphocytes, None) , ( DNA: palindromic octamer sequence, None) , ( DNA: Egr-1/ Sp1 site, None) , ( DNA: Sp1 site, None) , ( DNA: POS, None) , ( DNA: Sp1 site, None) , ( DNA: tandem CRE motifs, None)
