title: The integrin alpha v gene: identification and characterization of the promoter region.
abstract: We isolated a 15.5 kilobase pair DNA fragment that contains the 5' end of the human vitronectin receptor alpha subunit (alpha v) gene. The nucleotide sequence of the 5' flanking region, first exon and part of the first intron of the alpha v gene was determined. The sequence showed that the 5' end of the alpha v gene lies within a CpG island. The transcriptional initiation site was mapped 169 base pairs upstream of the alpha v translational initiation site. The 5' flanking region of the alpha v gene does not contain TATA or InR transcriptional control elements but does contain four Sp1 binding sites, two Ets binding sites and one GATA binding site. The identified alpha v gene 5' flanking region directed the expression of human growth hormone in transfected HeLa cells. Successive deletions of the 5' flanking region demonstrated a 222 bp region that exerts a strong positive effect on alpha v promoter activity.
