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; DNA: palindromic octamer sequence; DNA: Egr-1/ Sp1 site; DNA: Sp1 site; DNA: POS; DNA: Sp1 site; DNA: tandem CRE motifs
