A PMA responsive element was localized to a region between -319 and -219 bp upstream of the initiation codon and co-transfections with transcription factor expression plasmids for AP-2 and Sp1 resulted in augmented ASM promoter activity , which was abolished when the binding sites for these two factors were deleted.
 binding sites, transcription factor expression plasmids, Sp1, PMA responsive element, -319 and -219 bp upstream, AP-2
