Here we report that the tissue specificity of this promoter is also mediated by sequences in a region II (bp -88 to - 59), which lies 10 bp upstream from the PU.1 -binding site .
 ( DNA: region II, None) , ( protein: PU.1, None) , ( DNA: promoter, None) , ( DNA: PU.1 -binding site, None) , ( DNA: 10 bp upstream, None)
