Fig. 1From: Nitric Oxide Inhibits Endothelial IL-1β-induced ICAM-1 Gene Expression at the Transcriptional Level Decreasing Sp1 and AP-1 ActivityTranscription factor binding sites of the murine ICAM-1 promoter. One zinc finger protein (ZIP) binding site, three AP-1 binding sites, two Sp1 and NF-κB sites, respectively and one AP-3 binding site have been identified (15,16). Numbering is relative to the translation start-site.Back to article page
