Fig. 1.
Schematic representation of the murine (gray) and human (white) GPIIb promoter fragments extending from −899 and −813 to +32 bp, respectively.
Nucleotide position of the different sites and elements are indicated from the initiation start site. Boxes represent GATA sites; circles, Ets sites; and diamonds, the repressor elements. The human enhancer was delimited by an arrow.
