This transgene consists of the human keratin 14 promoter, intron 2 of the rabbit beta-globin gene, the complete early region and parts of the noncoding region and the L2-open reading frame of human papillomavirus type 8 (HPV8), and keratin 14 polyadenylation sequence. The keratin 14 promoter drives expression of the transgene in basal cells of the squamous epithelium. This record represents pooled data or data where the line number is not specified.
