CHARACTERIZATION OF THE GENOMIC STRUCTURE AND PROMOTER OF THE MOUSE NAD(-DEPENDENT 15-HYDROXYPROSTAGLANDIN DEHYDROGENASE GENE())

The mouse NAD(+)-dependent 15-hydroxyprostaglandin dehydrogenase (15-P GDH) gene and its 5'-flanking region was cloned from a 129 mouse ES ba cteriophage P1 genomic library, The gene contains 7 exons and 6 intron s and is 11.3 kb in length. The transcription initiation site was mapp ed at 35 bases upstream from the ATG start codon. The nucleotide seque nce of the 1.6 kb promoter region contains two TATA boxes and a number of potential regulatory elements including Sp1, CRE, GRE, AP1, AP2, N F-IL6 and estrogen receptor binding site. Studies of the promoter's ac tivity showed that the first 400 nucleotides of 5'-flanking region eff iciently drove the transcription of the luciferase reporter gene in U9 36 cells upon stimulation with a phorbol ester.
