In vivo footprinting identified protected regions over the known high affinity B cell lineage-specific activator protein (BSAP) site , the low affinity BSAP site , a SP1/Egr-1 site termed the CD19 GC box , and two novel sites named the AT box and PyG box .
 ( DNA: AT box, None) , ( DNA: SP1/Egr-1 site, None) , ( protein: B cell lineage-specific activator protein, None) , ( DNA: CD19 GC box, None) , ( DNA: low affinity BSAP site, None) , ( DNA: PyG box, None) , ( DNA: B cell lineage-specific activator protein (BSAP) site, None)
